Prove the two triangles are . Step 3: Identify the corresponding sides and angles. Step 4: What is true about and ? Step 5: What types of angles were formed when the angle bisector intersected ? What does this mean about the angle bisector? Once we triangles are congruent, we know that their corresponding parts (angles and sides) are congruent. We can abbreviate this is in a proof by using the reasoning of: CPCTC (Corresponding Parts of Congruent Triangles are Congruent). To Prove Angles or Sides Congruent: Prove the triangles are congruent (using one of the above criteria) States that the angles/sides are congruent because of CPCTC. To Prove Midpoint/Bisect/Perpendicular/Parallel: the triangles are congruent (using one of the above criteria) State that the necessary angles/sides are congruent because of CPCTC.
