Geometry 5.1 SWLT: Identify Congruent Triangles and Corresponding Parts
Congruent Figures • Two figures are congruent if… • All pairs of corresponding angles are congruent • All pairs of corresponding sides are congruent
Identifying Corresponding Parts PHD MBA List the Congruent Corresponding Parts P M H B D A P • 1st Pair of Angles • 2nd Pair of Angles • 3rd Pair of Angles • 1st Pair of Sides • 2nd Pair of Sides • 3rd Pair of Sides H D M B A
Using Properties of Congruent Triangles • Given: ABC XYZ • What is the mA • 95° • What does XY = • 10 • Order Matters!!! A 10 12 C B Y 95° X Z
