Question

Question 3
Can the angles ${110}^{\circ },{80}^{\circ },{70}^{\circ }and{95}^{\circ }$ be the angles of a quadrilateral? Why or why not?

Answer 1

No, we know that sum of all angles of a quadrilateral is ${360}^{\circ }$.
Here, sum of the angles = ${110}^{\circ }+{80}^{\circ }+{70}^{\circ }+{95}^{\circ }={355}^{\circ }\ne {360}^{\circ }$.
So, these angles cannot be the angles of a quadrilateral.
