The theorem CPCTC tells that when two triangles are congruent then their corresponding sides and angles are also said to be congruent. For example, triangle ABC and triangle PQR are congruent triangles therefore according to the theorem the sides AB = PQ, BC = QR, and CA = RP. Also ∠A = ∠P, ∠B = ∠Q, and ∠C = ∠R.an algebraic sentence stating a relationship between two quantities other than that they are equal to each other. a statement formed by switching the hypothesis and the conclusion of a conditional. two line segments that have the same length. in a triangle, the angle formed by two given sides of the triangle.

Consider the triangles in the figure. • ∆STQ: This is an ____ __ triangle because all the angles are less than 90°. Since TQ ≅ QS, it’s an isosceles triangle. So, it’s an isosceles acute triangle. • ∆PQR: This is a right isosceles triangle. • ∆SQP: Angle Q is an obtuse angle. Since SQ ≅ QP, it’s an4. Calculate the proportion of the side lengths between the two triangles. To use the SAS theorem, the sides of the triangles must be proportional to each other. To calculate this, simply use the formula AB/DE = AC/DF. Example: AB/DE = AC/DF; 4/2 = 8/4; 2 = 2. The proportions of the two triangles are equal. 5.
