Definitions

100

two angles are complementary if they add up to

90 degrees

200

Two angles are supplementary if they add up to

180

300

Angle angle OUTSIDE the triangle is called

exterior angle

400

two angles that match are called

corresponding angles

500

two angles that are equal in value are called

congruent angles

Triangles

100

the theorem that states that the internal degrees of a triangle add up to 180 degrees is called

Triangle Sum Theorem

200

The Postulate (statement) that two triangles are similar if they have two sets of corresponding angles that are congruent is called

Angle-Angle Similarity Postulate

300

Two Triangles are similar if they have at least how many congruent corresponding angles?

2

400

True or false: The One of the remote interior angles in a triangle can be greater than the exterior angle

False

500

If a Triangle has angle measures 25 and 27, what is the third angle

128 degrees

Equations and triangles

100

Solve: 3x + 4 = 10

x = 2

200

the angles in a triangle measure 2x, 3x and 4x. Write an equation to determine the angle measures

2x + 3x +4x = 180

300

If I draw a triangle with one angle that measures 40 degrees, what is the value of that angle's exterior angle

140 degrees
