Triangles
When two angles in one triangle are congruent to two angles in another triangle this is the relationship between the triangles.
What are similar triangles
Find the supplement of 82 degrees
What is 98 degrees?
Angles on opposite sides of the vertex when lines intersect
What are Vertical Angles?
A pair of angles are same-side interior angles. One of the angles measures 68 degrees. Find the measure of the other.
What is 112 degrees?

Complementary angles
Triangle A has angles measuring 50 degrees and 100 degrees. The measure of the 3rd angle in the triangle.
What is 30 degrees?

What is 78 degrees?
Lines that are the same distance apart that will never intersect
Parallel Lines

What are 60 and 120 degrees?
Angles that are outside of a triangle, and adjacent to the interior angles.
What are exterior angles?
An exterior angle of a triangle measures 110 degrees. One of the nonadjacent interior angles measures 50 degrees. Find the measure of the other nonadjacent angle.
What is 60 degrees?
Two angles that are formed by two intersecting lines that share a vertex, but not a side.
What are vertical angles?
When two triangles are similar, their angles are congruent and their corresponding sides are .....
What is proportional?
These two types of angles are supplementary
What are same side interior and same side exterior angles?
Angles that lie on the same side of the transversal and on corresponding sides of parallel lines.
What are corresponding angles?
Two interior angles of a triangle measure 33 and 89 degrees. Find the measure of the third interior angle.
What is 58 degrees?
