What is the definition of congruence in geometry?

Back

Congruence means that two figures have the same shape and size.

Front

State the Transitive Property of Segment Congruence.

Back

If segment AB ≅ segment CD and segment CD ≅ segment EF, then segment AB ≅ segment EF.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint called the vertex.
