Know the vocabulary and how to identify the geometric terms
from figures. (Like #1 on the quiz) All vocabulary words are on
the next page of this guide.
Be able to write equations for complementary angles by: adding
the angles that are complementary together to = 90, then
solve.
Supplementary Angle Equations: Add angles together to = 180,
then solve the equation.
Vertical Angles are Congruent, so in equations: Make one angle
= to the other angle, then solve the equation.
Triangle Equations: Add all angles together to = 180, then
solve.
We solve scale drawing problems by writing proportions and
solving them.
3-dimensional Figures:
Prism rectangular faces + 2 parallel bases – name by shape of
base.
Cylinder: 2 parallel congruent circle bases (Like a can)
Pyramid: 1 polygon base + triangular faces – name by shape
of the base.
Cone: Circular Base, 1 vertex
Sphere: Like a ball
