Under this criterion, if the two angles and the side included between them of one triangle are equal to the two corresponding angles and the side included between them of another triangle, the two triangles are congruent. This triple ine symbol is what we use in Australia; however some other countries use an equals sign with a squiggly “tilda” line added to the top of it. The following worksheet has basic multiple choice questions on Congruent Triangles. The following video shows why there is not an SSA Rule for congruent triangles. In addition, the two triangles "share" side . Two triangles are congruent if two matching angles are equal and a matching side is equal in length. In another lesson, we will consider a proof used for right triangles called the Hypotenuse Leg rule. When we say the Triangles are Congruent using their letters, we need to make sure the order of the letters matches the path around the two triangles correctly. Under this criterion, if the two angles and the non-included side of one triangle are equal to the two corresponding angles and the non-included side of another triangle, the triangles are congruent. Angles can be oriented in any direction on a plane and still be congruent. Congruence is the term used to describe the relation of two figures that are congruent.
