Triangles Worksheets

Our triangles worksheets will help your students to identify, match, and draw triangles. Children will also be challenged to find triangles in their classroom environment. How many can they find? Triangles aren’t as plentiful as circles, squares, and rectangles, so you may need to make sure there are plenty for them to find. The “tri” in triangle means that these shapes have three sides. If you turn a triangle with three equal sides around, which side is up? Do triangles have to have three equal sides to be called a triangle?
