Unit 2: Geometric Angle Theorems
2.1 Angle Relationships G.2.A, G.2.B, G.2.D
I can correctly identify the relationship between pairs of angles formed by intersecting lines, both parallel
and perpendicular, pairs of lines.
This means I can
 Identify complementary, supplementary, alternate interior/exterior, same-side interior/exterior (cointerior/exterior), and corresponding angle pairs
 Calculate the measure of angles given one or two angles on a diagram using the angle relationships
identified above
 Know, prove, and apply theorems about parallel and perpendicular lines.
2.2 Triangle Angle Relationships G.3.A
I can correctly identify the relationship between angles formed inside a triangle.
This means I can
 Use the Triangle Angle Sum Theorem to find missing angles in a triangle
 Know and apply basic postulates and theorems about triangles and special lines, line segments, and
rays associated with triangles
