What does AA stand for in triangle similarity?

Back

Angle-Angle similarity criterion.

Front

What is the SSS similarity criterion?

Back

Side-Side-Side similarity criterion states that if the sides of one triangle are proportional to the sides of another triangle, then the triangles are similar.

Front

What is the SAS similarity criterion?

Back

Side-Angle-Side similarity criterion states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What is a scale factor in geometry?

Back

A scale factor is a number that scales, or multiplies, some quantity.

Front
