Question

The sum of the interior angles of a quadrilateral is
a. 90°
d. 60°
c. 180°
b. 360°​

Answer 1

●The sum of the interior angleas of a quadrilateral is 360°

Answer 2

The sum of interior angles of quadrilateral is 360'

we know,,

Interior angles of a quadrilateral are the angles subtended at the inside of the figure •

If we draw a diagonal, then it divides quadrilateral in the two triangles,

sum of interior angles of triangle =180'

therefore there are two triangles having the measure of sum of interior angles Is 180'

for the two triangles = 180'+ 180'

= $\boxed{\textbf{\large{360 degree}}}$
