Properties of a triangleA triangle has three sides, three angles, and three vertices.The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle.
Properties of a triangleA triangle has three sides, three angles, and three vertices.The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle.The sum of the length of any two sides of a triangle is greater than the length of the third side.

Properties of a Triangle
Triangle properties angle sides
- A triangle has three , three , and three .
- The sum of the three interior angles of a triangle is always 180°.
- The sum of the length of two sides of a triangle is always greater than the length of the third side.
- A triangle with vertices P, Q, and R is denoted as △PQR.
- The area of a triangle is equal to half of the product of its base and height.
Different Types of Triangles
To classify triangles according to their angles, we measure each of its interior angles. Triangles can be classified by angles, as:
Acute Triangle
Right Triangle
Obtuse Triangle
Types of triangles by angles
An acute triangle has all interior angles acute (less than 90°), a right triangle has one right angle (equal to 90°) and an obtuse triangle has one obtuse angle (greater than 90°).
