Here guys Thanks :D
Congruent triangles are similar figures with a ratio of similarity of 1, that is
1
1
. One
way to prove triangles congruent is to prove they are similar first, and then prove
that the ratio of similarity is 1. In these sections of the text the students find short
cuts that enable them to prove triangles congruent in fewer steps, by developing
five triangle congruence conjectures. They are SSS! , ASA! , AAS! , SAS! , and
HL ! , illustrated below.

Triangles are congruent to each other if they have the same 3 sides in length and have the same interior angles.
Isosceles triangle
no it makes a square.
A. Corresponding parts of similar triangles are similar.B. Alternate interior angles are supplementary.C. Alternate interior angles are congruent.D. Corresponding parts of congruent triangles are congruent
If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
