theorems.
(2.) Logical
congruent?
What are some of
the defining
characteristics of
a triangle?
What
characterizes
different types of
triangles?
G.30 Investigate, justify, and apply
theorems about the sum of the
measures of the angles of a triangle
G.32 Investigate, justify, and apply
theorems about geometric
inequalities, using the exterior angle
theorem
G.31 Investigate, justify and apply
the isosceles triangle theorem and its
converse
G.33 Investigate, justify and apply
the triangle inequality theorem
G.34 Determine the longest side of a
triangle given the three angle
measures or the largest angle given
the lengths of three sides of a triangle
arguments consist of
a set of premises or
hypotheses and a
conclusion.
(3.) Reasoning and
proofs are
fundamental to
mathematics and
help us prove or
disprove various
conjectures.
(4.) Only 1
counterexample is
necessary to prove a
statement false, but 1
example does not
prove the truth value
of a statement.
(1.) If two triangles
are congruent, then
their corresponding
sides have equal
lengths as one
proceeds around
both triangles (2.) If
two triangles are
congruent, their
corresponding
interior angles (or
angles opposite to the
corresponding sides)
have equal measures
as you move around
the two triangles.
(1.) The sum of the
angles for all
triangles—obtuse,
isosceles, or right—is
180 degrees. (2.)
Isosceles triangles
has two equal sides
or angles (3.) In an
isosceles triangle, the
angles opposite
congruent sides are
congruent. (4.) The
relative length of a
side corresponds to
the relative measure
of the angle opposite
it. That is, the largest
side is opposite the
largest angle; the
smallest side is
opposite the smallest
angle, etc
(1.) In any triangle, if
one of the sides is
produced, then the
exterior angle is
greater than either of
the opposite interior
angles. The exterior
angle is also equal to
the sum of the 2
opposite interior
angles.
(2.) In order to form a
triangle, the sum of
the 2 smallest sides
must be greater than
the length of the 3rd
side.

What does it
mean for
geometric figures
to be similar?
How can I prove
similar triangles?
What are the
characteristics of
similar triangles?
G.42 Investigate, justify, and apply
theorems about geometric
relationships, based on the
properties of the line segment joining
the midpoints of two sides of the
triangle
G.44 Establish similarity of triangles,
using the following theorems: AA,
SAS, and SSS
G.45 Investigate, justify, and apply
theorems about similar triangles
G.46 Investigate, justify, and apply
theorems about proportional
relationships among the segments of
the sides of the triangle, given one or
more lines parallel to one side of a
triangle and intersecting the other
two sides of the triangle
G.47 Investigate, justify, and apply
theorems about mean
proportionality: (1)the altitude to the
hypotenuse of a right triangle is the
10 days
(1.) If we know that a
line joins the
midpoints of 2
sides in a
triangle, we can
make
generalizations
about the
relationship of
this line to the 3rd
side.
(1.) Triangles are
similar if and only if
their sides are in
proportion (2.)
Corresponding angles
will still be congruent
(as opposed to in
proportion) in similar
triangles (3.) AAA

mean proportional between the two
segments along the hypotenuse (2)
the altitude to the hypotenuse of a
right triangle divides the hypotenuse
so that either leg of the right triangle
is the mean proportional between
the hypotenuse and segment of the
hypotenuse adjacent to that leg
similarity, not
congruence.
(1.) If a line is parallel
to one side of a
triangle and
intersects the other
sides in two distinct
points, then it
separates these sides
into segments of
proportional lengths
(1.) The altitude to
the hypotenuse of a
right triangle forms
two triangles that are
similar to each other
and to the original
triangle
(2.) The altitude to
the hypotenuse of a
right triangle is the
mean proportional
between the
segments into which
it divides the
hypotenuse.
Transformations

How can I
transform
geometric figures
in the coordinate
grid?
G.54 Define, investigate, justify, and
apply isometries in the plane

glide reflections) Note: Use proper
function notation.

the coordinate plane

transformation which

questions
How do the
different types of
transformations
affect the figures?
Investigate, justify, and apply the
properties that remain invariant
under translations, rotations,
reflections, and glide reflections
G.56 Identify specific isometries by
observing orientation, numbers of
invariant points, and/or parallelism
G.57 Justify geometric relationships
(perpendicularity, parallelism,
congruence) using transformational
techniques (translations, rotations,
reflections) G.58 Define, investigate,
justify, and apply similarities
(dilations and the composition of
dilations and isometries)
G.59
Investigate, justify, and apply the
properties that remain invariant
under similarities G.60 Identify
specific similarities by observing
orientation, numbers of invariant
points, and/or parallelism G.61
Investigate, justify, and apply the
analytical representations for
translations, rotations about the
origin of 90º and 180º, reflections
over the lines x=0, y=0 , and y=x ,
and dilations centered at the origin
another way,
isometries produce
congruent figures.
(1.) We can use our
existing knowledge of
perpendicularity,
parallelism, and
congruence to make
generalizations about
the results of various
transformations.
(1.) Not all
transformations are
isometries. Dilations
produce figures that
are similar, but not
congruent.
(2.) It is possible to
perform more than
one transformation
on the same figure to
obtain the image
from the preimage
Circles and Loci
5/4 – 5/14
What is a circle?
How can I graph
a circle on a
coordinate grid?
G.71 Write the equation of a circle,
given its center and radius or given
the endpoints of a diameter
G.72 Write the equation of a circle,
given its graph
Note: The center is an ordered pair of
integers and the radius is an integer.
G.73 Find the center and radius of a
circle, given the equation of the circle
in center-radius form
G.74 Graph circles of the form
( x  h)2  ( y  k )2  r 2
G.22 Solve problems using
compound loci
G.23 Graph and solve compound loci
10 days
(1.) Reflections result
in symmetry about a
point or line.
(1.) A circle includes
all points equidistant,
r, from the center (h,
k).
The equation of a
circle includes the
center point and
radius
(1.) We can figure out
the location of the
center and the length
of the radius of a
circle simply by
looking at the
equation of a circle.
(2.) The center (h, k)

in the coordinate plane
has the opposite sign
from how it appears
in the equation
(3.) The use of square
roots allows us to
find the center of the
circle.
(1.) Loci are sets of
points that satisfy 1
given condition,
usually involving a
distance from
another object. There
are 5 main scenarios
that loci problems
involve.
(2.) Compound loci
are sets of points that
satisfy more than 1
given condition.
