What is the sum of the interior angles of a triangle?
Explanation
The angle sum of a triangle will always be equal to 180°.
The angle sum of a quadrilateral is equal to 360°
And a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral
Its angle measures should be half as well. Half of 360° is 180°
