Furthermore, the exterior angle is equal to the sum of the non-adjacent interior angle. Question 5: Do interior angles add up to 180º? Answer: Two angles that add up to 180º are known as supplementary …

Sum of angles is given by the formula (n−2)×180, where n = no.of sides

Correspondingly, the distinction between the two sides of a triangle is less than the length of the third side. Q: How to find the interior angle and understand what is a triangle? A: To find the sum of the …

An exterior angle of a triangle is equal to the sum of the opposite interior angles. If the equivalent angle is taken at each vertex, the exterior angles always add to 360 degrees.

Prove that the sum of the angles of the triangle is 180∘.

The sum of all angles of a triangle is 180, hence all angles of a triangle are always supplementary angles. View Solution

In an isosceles triangle, the base angles are equal. The vertex angle is 40o. What are the base angles of the triangle? (Remember, the sum of three angles of a triangle is 180o).

The sum of two angles of a triangle is 116 ∘ and their difference is 24 ∘ Find the measure of each angle of the triangle.

In an isosceles triangle, the vertex angle is twice the base angle. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees).

In a triangle, two interior angles are equal to 70 degrees each. what is the third interior angle ?
