Question

draw polygon on square dots it also draw on congruent figures in different direction and Mirror image of it

Answer 1

Two polygons are congruent if they are thesame size and shape - that is, if their corresponding angles and sides are equal. Move your mouse cursor over the parts of each figure on the left to see thecorresponding parts of the congruent figureon the right.
Reflected triangles can be congruent. To be congruent two triangles must be the same shape and size. However one triangle can be reflected, that is, flipped over with respect to the other. As long as they are otherwise identical, the triangles are still congruent.
