CORRSEPONDING
ANGLES POSTULATE
• If a transversal
intersects two
parallel lines,
then
corresponding
angles are
congruent.
THEOREM 2-4
• All right
angles are
congruent.
THEOREM 10-11
• (Area of a circle)
• The are of a circle is
the product of π and
the square of the
radius.
• A=πr^2
r
TRIANGLE
• Three sided figure
whose angles add to
be 180.
ISOSCELES
TRAPEZOID
• Quadrilateral with
one pair of parallel
sides whose legs
are congruent.
CIRCLE
• Set of all points in a
plane that are a
given distance, the
radius, from a given
point, the center.
CONE
• 3D figure with a
circular base, a
vertex not in the
plane of the
surface, and a
curved lateral
surface.
CYLINDER
• 3D figure with two
congruent circular
bases that lie in
similar planes.
SUPPLEMENTARY
ANGLES
• Pairs of angles
that add to equal
180 degrees.
REFLECTION
• When a shape is
flipped across a
line and faces the
opposite direction
ALTITUDE OF A
TRIANGLE
• Perpendicular
segment from a
vertex to the line
containing the
side opposite that
vertex.
TRANSLATION
• Transformation
that moves points
the same
distance and in
the same
direction.
CENTROID OF A
TRIANGLE
• The point of
intersection of the
medians of the
triangle.
OBTUSE ANGLE
•
Angle
whose measure is
more than 90
degrees and less
than 180 degrees.
RADIUS
• Any segment with
one endpoint on
the circle and the
other endpoint at
the center of the
circle.
SKEW LINES
• Lines that do not
lie on the same
plane and will
never intersect.
INDIRECT
MEASUREMENT
• Way of measuring
things that are
difficult to measure
directly by
measuring the
distances shown and
using proportions of
similar figures you
can find
measurements.
VERTICAL ANGLES
• Two angles
whose sides form
opposite rays.
Vertical angles
congruent.
