Expert Answer:

Equality of triangle relates to congruence of triangles. Two triangles are said to be equal or congruent if they are of same shape and same size.

 

In the above figure, triangles ABC and XYZ are congruent figures.

 

Two triangles are said to be similar, if they are of the same shape and may or may not of same size.

 

In the above figure, triangles ABC and XYZ are of same shape  (The ratio of corresponding sides of the triangles are equal. Here it is 2:3). But they are not of same size. Here, triangles ABC and XYZ are similar figures.
