Solving Corresponding Parts of Congruent Triangles

In solving the corresponding parts of congruent triangles, see to it first if the two triangles are congruent and what are the corresponding sides and corresponding angles are congruent. Apply your previous knowledge about the theorems and postulates of triangle congruence.

  1. What postulate/theorem did you use to solve for the missing side?

SAS theorem

  • How did you solve for x?

Subtract the sum of the two angles from 180°.

The sum of all the angles of a triangle always

Equal to 180°.Write down the difference you

Found between two subtracted angles with 180°

  • How did you solve for each side of the triangle?

          By subtracting two angles from 180°

  • What are the congruent sides of   ∆ABC and ∆PQR, of ∆DES and  ∆MAR?

 AB = PQ, BC = QR, AC= PR.

and DE = MA, ES = AR, DS = MR.

In solving the corresponding parts of congruent triangles, see to it

first if the two triangles are congruent and what are the corresponding sides

and corresponding angles that are congruent. Apply your previous

knowledge about the theorems and postulates of triangle congruence.
