One way is to trace around one of the triangles and place it over the other. If<span> the angles and sides match exactly, then the </span>two<span> are </span>congruent<span>. But there is another way to </span>tell<span>. </span>If two<span> triangles have </span>congruent<span> corresponding parts, then the triangles are </span>congruent<span> triangles. </span>
Congruent shapes must have the same shape and size. To determine if two figures are congruent, measure all of their angles and side lengths. If each pair of corresponding angles and sides have the same measure, then the figures are congruent.
