What is the Classification of Triangles in Geometry? Triangles are classified according to 2 groups i.e. sides and angles and are of six types in total. Based on their sides, the 3 triangles are classified as equilateral triangles, isosceles triangles, and scalene triangles.
- Right Triangles. A right triangle has one 90° angle and a variety of often-studied topics: Pythagorean Theorem. Pythagorean Triplets. Sine, Cosine, Tangent. Pictures of Right Triangles.
- Equilateral triangle. The Equilateral triangle shown on the left has three congruent sides and three congruent angles. Each angle is 60°.
- Isosceles triangle. The Isosceles triangle shown on the left has two equal sides and two equal angles.
- Scalene Triangle. The Scalene Triangle has no congruent sides. In other words, each side must have a different length.
A triangle has three sides and three angles. The three angles always add to 180°. Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles: How to remember? Alphabetically they go 3, 2, none:
