What postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent?

Back

SSS (Side-Side-Side) Postulate.

Front

What is the slope of parallel lines?

Back

The slope of parallel lines is the same.

Front

How can a line be named?

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are vertical angles?

Back
