Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180°.

Front

What is the Corresponding Angle Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

What does AA ~ stand for in similarity?

Back

AA ~ stands for Angle-Angle similarity, which states that if two angles of one triangle are congruent to two angles of another triangle, the triangles are similar.

Front

What is the SAS ~ similarity criterion?

Back

SAS ~ (Side-Angle-Side similarity) states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are congruent, the triangles are similar.

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 corresponding sides are proportional.
