4. Congruent Polygons Congruent segments have the same length Congruent angles have the same measure Congruent polygons have the same size and shape

5. Congruent Polygons Congruent segments have the same length Congruent angles have the same measure Congruent polygons have the same size and shape The corresponding parts of congruent polygons are in the same position in different figures. To name congruent polygons, list the corresponding parts in the same order.

6. Congruent Polygons You can tell if two triangles are congruent by using one of the following proofs

7. Congruent Polygons You can tell if two triangles are congruent by using one of the following proofs 1.side-side-side (sss) – all of the sides of one triangle are congruent to the sides of a second triangle

8. Congruent Polygons You can tell if two triangles are congruent by using one of the following proofs 1.side-side-side (sss) – all of the sides of one triangle are congruent to the sides of a second triangle 2.side-angle-side (sas) – two sides and the angle between them of one triangle are congruent to two sides and the angle between them of a second triangle
