Identify the Triangles Worksheets - Free Printable

Explanation:
Let’s go through each triangle one by one and identify its type based on its sides and angles.

1. This triangle has one angle that looks like it’s 90 degrees (a right angle), so it’s a Right Triangle.
2. All three sides look equal, so it’s an Equilateral Triangle.
3. This triangle has two sides that are the same length, so it’s an Isosceles Triangle.
4. This triangle has all sides equal — it’s Equilateral Triangle.
5. Two sides are the same — it’s Isosceles Triangle.
6. One angle looks like a right angle — this is a Right Triangle.
7. Two sides are the same — this is Isosceles Triangle.
8. Two sides are the same — this is Isosceles Triangle.
9. Two sides are the same — this is Isosceles Triangle.
10. Two sides are the same — this is Isosceles Triangle.
11. Two sides are the same — this is Isosceles Triangle.
12. All sides look equal — this is Equilateral Triangle.

Now let’s match each triangle to the correct letter:

- 1. Right Triangle → A
- 2. Equilateral Triangle → B
- 3. Isosceles Triangle → C
- 4. Equilateral Triangle → B
- 5. Isosceles Triangle → C
- 6. Right Triangle → A
- 7. Isosceles Triangle → C
- 8. Isosceles Triangle → C
- 9. Isosceles Triangle → C
- 10. Isosceles Triangle → C
- 11. Isosceles Triangle → C
- 12. Equilateral Triangle → B
