Congruent figures have the same size and shape which polygons appear to be congruent

"The two polygons are said to be congruent if they are of same size and have the shape."

Explanation:

When the two polygons are having same size as well as the shape and also with equal corresponding angles and sides. When the cursor is moved over the parts in both the figures on the left to visualize the corresponding part of congruent figure in the right. When all the sides and angles are congruent are said to be the congruent polygon. To know whether the congruent is polygon or not, first we should count the number of sides, then look at the corresponding sides whether they are of same length and then check the interior angles are of same measure or not.
