7.M.G.A.02: Draw geometric
shapes with given conditions.
Focus on constructing triangles
from three measures of angles
or sides, noticing when the
conditions determine a unique
triangle, more than one
triangles or no triangle.
I can describe and draw
different polygons base on their
properties.
*What are examples of unique
polygons?
*How do their specific
properties make them unique?

triangle, scalene triangle
A triangle is a closed figure with
three sides.

Draw a quadrilateral with
congruent sides and no right
angles. What type of
quadrilateral did you draw?
Using a protractor
1) Generally the straight
side of the protractor
is a ruler that can be
used to measure a
straight line
2) You can measure the
degrees in an angle by
placing the vertex on
the circle/dot and one
of the rays onto the
line.
3) Count up from the
line, starting at zero
until you reach the
next ray.

yesterday If necessary)
Other polygons and regular
shapes
Quadrilaterals

4 sides

The sides have to be
straight, and it has to
be 2-dimensional

Parallelograms –
opposite sides are
congruent parallel

Rectangle – opposite
sides are congruent
and parallel. Must
have 4 right angles

Rhombus – all 4 sides
are congruent and
Shapes that are not triangles (3
sides) and that are not
quadrilaterals (4 sides) are
named by their sides
5 sides: Pentagon
6 sides – Hexagon
7 sides: Heptagon or
Septagon
8 sides: Octagon
9 sides: Nonagon
10 sides: Decagon
Anything bigger than
10 sides will generally
be called an “n-gon”
Students will complete their
CFA

Theorem. Also, discuss the
triangle side theorem which
states that the two shorter sides
when added up must be greater
than the length of the longest
side.

Summary
Sorting Activity – Students will
use notes and protractors to
determine which categories to
sort their triangles into
categories
opposite angles are
equal

Square = all 4 sides
are congruent and all
4 angles are 90°

Trapezoid – only one
pair of parallel sides

Kite – two adjacent
sides are congruent
and the angles are
equal where the pairs
meet

The only “REGULAR”
quadrilateral is a
square, so all other
quadrilaterals are
irregular.

Interior angles add up
to 360°
Use website to view examples
of different quadrilaterals:

ometry/quadrilateralsinteractive.html
*Check for correct usage of the
protractor
*Check for correctly sorted
groups by side
*Check for correctly sorted
groups by angle
Students are able to look at
various quadrilaterals and
correctly name them.
Students determine if three
given lengths will form a
triangle. Will they form a right
triangle?
Given the three lengths,
determine if a triangle can be
formed.

where “n” is the
number of sides in the
polygon.
Regular vs Irregular
A regular polygon is a
figure in which all of
the sides and all of the
angles are congruent
(an equilateral
triangle and a square
are examples of
regular polygons)
An irregular polygon
has the given number
of sides, but they are
not all congruent.
Students draw, label and define
the various types of polygons
including examples of regular
and irregular polygons.
Students correctly identify
polygons when shown their
image.

and sort them into assignment
type -> Classwork, assessments,
homework.
-Students prepare by filling out
their conference agenda
-Fill out the handout with
appropriate goals (discuss how
to set a good goal – one that is
specific with how they plan to
attain that goal.)
After students have completed
their corrections they will write
a letter of invitation to their
family members.
Emphasize the value of the
conference; discuss what you
are most proud of and what
work still needs to be done.
Make sure that students
understand should not make
excuses but must present
samples of work to parents that
accurately depict their
performance – both successes
and challenges
