It can help kids identify and classify shapes correctly. Understanding the different types of triangles is an important part of learning geometry. In an obtuse triangle, the side opposite the obtuse angle is the longest side. Obtuse triangles: Obtuse triangles have one angle that is greater than 90 degrees, which is called an obtuse angle.

This means that all three sides of an acute triangle are acute angles. The Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the legs, is often used to solve problems involving right triangles.Īcute triangles: Acute triangles have three angles that are all less than 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. Right triangles: Right triangles have one angle that measures 90 degrees, which is called a right angle. Because scalene triangles are irregular, they can have a variety of angles, ranging from acute to obtuse.

Scalene triangles: Scalene triangles have three different sides and three different angles. Isosceles triangles can be acute, right or obtuse. The two equal angles are opposite the two equal sides. The third side and angle may be different. Isosceles triangles: Isosceles triangles have two equal sides and two equal angles. They are often used in geometry because they are symmetrical and have some interesting properties. All angles in an equilateral triangle are 60 degrees. This sheet presents different types of triangles based on sides (Equilateral, Isosceles, and Scalene) and angles (Right, Acute, and Obtuse).Įquilateral triangles: Equilateral triangles have three equal sides and three equal angles.
