# What do the angles in a triangle add up to?

In a Euclidean space, the sum of angles of a triangle equals 180 degrees. Whether a triangle is an acute, obtuse, or a right triangle, the sum of the angles will always be 180º. Thus, the angle sum property states that the sum of the angles of a triangle is equal to 180º.

## Answer: In a triangle, the three interior angles always add to 180°

Let us see the formula used to determine the sum of angles in a triangle.

**Explanation:**

The formula for calculating the sum of interior angles of a polygon is **( n − 2 ) × 180°, **n is the number of sides of a polygon.

Sum of angles in a quadrilateral = (3 - 2) × 180° = 1 × 180° = 180°

⇒ The sum of all interior angles is 180°.
