What does AA~ stand for in triangle 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, then the triangles are similar.

What does SSS~ stand for in triangle similarity?

Back

SSS~ stands for Side-Side-Side similarity, which states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

What is the significance of corresponding angles in triangle similarity?

Back

Corresponding angles are angles that are in the same relative position in different triangles. If they are congruent, it helps establish triangle similarity.

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. If the lines are parallel, these angles are congruent.
