When the sides of a quadrilaterals are extended and the exterior angles are produced. A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. Let the unknown angle be x.

Quadrilateral Interior & Exterior Angle Sum Theorems (V2

Hence the required sum of all the angles of a concave quadrilateral is 360 ∘. A diagonal line extends from angle 8 to form angle 2. 50 ° + 20 ° + 10 ° + ∠adc = 360 °. The sum of four exterior angle is always 360 degrees.
