Congruent Figures

Congruent figures have the same size and shape. Congruent polygons have congruent corresponding parts - their matching sides and angles.

When you name congruent polygons, always list corresponding vertices in the same order.  ABC   QTR  A   Q  B   T  C   R AB  QT BC  TR AC  QR R

Name 3 pairs of corresponding sides. Name 3 pairs of corresponding angles. Can I say ? M A B N O Y

Triangles are congruent when they have three pairs of congruent corresponding sides and three pairs of congruent corresponding angles. Find two congruent triangles:

If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. A B C D E F  C   F

Can you conclude these figures are congruent?

Find the measure of the missing angles. The two figures are congruent.
