Triangles are a special shape in math, and we can group them in two main ways: by their side lengths and by their angles. Let’s take a closer look!
Equilateral Triangle: All three sides are the same length. For example, if each side is 5 cm, it’s an equilateral triangle.
Isosceles Triangle: This triangle has two sides that are equal. Imagine a triangle with sides of 3 cm, 3 cm, and 5 cm.
Scalene Triangle: All sides of this triangle are different lengths. For instance, a triangle with sides measuring 2 cm, 4 cm, and 6 cm.
Acute Triangle: In this type, all angles are less than 90°. Picture a triangle with angles of 30°, 60°, and 90°.
Right Triangle: This triangle has one angle that is exactly 90°. Think of a triangle with angles of 30°, 60°, and 90° — that one angle is a right angle!
Obtuse Triangle: One angle is greater than 90°. For example, a triangle with angles of 100°, 40°, and 40°.
Understanding these groups helps us see what makes each triangle special and how they fit into geometry!
