WebSep 4, 2024 · 2.1: The Congruence Statement. Two triangles are said to be congruent if one can be placed over the other so that they coincide (fit together). This means that congruent triangles are exact copies of each other and when fitted together the sides and angles which coincide, called corresponding sides and angles, are equal. WebNo, Yin is not correct. If x = 19, the measure of angle ABC = 4(19) - 12 = 64. Therefore, the two base angles measure 64°. An equilateral triangle is equiangular, so each angle would have to measure 60° because there are 180° in a triangle.

WebJan 25, 2024 · SSS Criterion for Similarity of Triangles. Suppose in two triangles, sides of one triangle are proportionate to the sides of the other triangle. In that case, their corresponding angles are equal, and hence the two triangles are similar. This criterion refers to the \ ( {\text {SSS}}\) (Side–Side–Side) similarity criterion for two triangles. WebA triangle has angle lengths 35 degrees, 120 degrees, and 35 degrees. A triangle has angle lengths 30 degrees, 120 degrees, and 20 degrees. b.
