U v x w 3. Congruent triangles are triangles having corresponding sides and angles to be equal. How to use cpctc (corresponding parts of congruent triangles are congruent), why aaa and ssa does not work as congruence shortcuts how to use the hypotenuse leg rule for right triangles, examples with step by step solutions

We already learned about congruence, where all sides must be of equal length.in similarity, angles must be of equal measure with all sides proportional. 20+ math tutors are available to help. Includes guided checklist and explanation for the ta.
