Front

What is the exterior angle of a triangle?

Back

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Front

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect, no matter how far they are extended.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a method to prove triangles are congruent.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a method to prove triangles are congruent when all three sides are equal.

Front

What is the definition of a perpendicular line?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size; their corresponding angles are equal and their sides are proportional.

Front

What is the Reflexive Property of Congruence?

Back

The Reflexive Property of Congruence states that any geometric figure is congruent to itself.

Front

What is the Substitution Property?

Back

The Substitution Property states that if two values are equal, one can be substituted for the other in any expression.
