Name Class Date [pic] Triangle Congruence by SSS and SAS 4-2 Reteaching You can prove that triangles are congruent using the two postulates below. Postulate 4-1: Side-Side-Side (SSS) Postulate If all three sides of a triangle are congruent to all three sides of another triangle, then those two triangles are congruent. If [pic], [pic], and [pic], then ∆JKL ( ∆XYZ. In a triangle, the angle formed by any two sides is called the included angle for those sides. Postulate 4-2: Side-Angle-Side

letter resembled an isoceles triangle. My letter has two sides that are the same length and two of base angles are the same in length. The definintion of an isoceles triangle is a triangle with two sides of equal length and two congruent base angles. The letter A I built and isoceles triangle are almost a perfect match. Another geometry concept that connectes with my letter, A was an acute angle. An acute angle is an angle that is less than 90 degrees. The triangle inside the letter A I constructed
