Congruent triangles examples pdf. Another way to state that triangle abc is congruent to triangle def is by using the following They have the same area and the same perimeter. B) if they are, name the triangle congruence (pay attention to proper correspondence when naming the triangles) and then identify the theorem or postulate (sss, sas, asa, aas, hl) that supports yo ur conclusion.
Congruency can be predicted without actually measuring the sides and angles of a. (there are answers on the last page of the pdf document). Given triangle abc is congruent to triangle def.
The comparison done in this case is between the sides and angles of the same triangle.when we compare two different triangles we follow a different set of rules. If we reverse the angles and the sides, we know that's also a congruence postulate. Note that in congruent triangles corresponding parts are equal and we write in short ‘cpct’ for corresponding parts of congruent triangles.
