Ever heard of similar triangles? As kids climb up the academic ladder, they’re introduced to a wide range of mathematical concepts, including basic geometry. To a large extent, geometry is fun. However, keeping up with the different types of shapes can be a tad overwhelming for any learner.

Similar triangles are an essential part of geometry that kids have to learn before moving on to a new concept. Unfortunately, it comes with a deluge of questions that need clarity, such as “What are similar triangles?” and “Are they the same as congruent triangles?”

On the flip side, a similar triangles worksheet helps to clear the air and teaches kids all they need to know about this topic. Let’s get into it, shall we?

## What Are Similar Triangles?

More often than not, learners mix up similar triangles with congruent ones. However, an entire world of difference exists between these two concepts.

Congruent triangles are triangles that have both the same shape and the same size. On the other hand, similar triangles have the same shape but may not have the same size. The sizes of similar triangles typically vary.

To ascertain the similarity of two triangles, you’ll need to check if they meet one of the following criteria:

- Three pairs of corresponding sides are proportional.
- Two pairs of corresponding angles are equal.
- Two pairs of corresponding sides are proportional, and the corresponding angles between them are equal.
