Question

If the sum of the two angles of a quadrilateral is ${180}^{\circ },$ What is the sum of the remaining two angles?

Answer 1

$\because$ Sum of four angles of a quadrilateral = ${360}^{\circ }$
and sum of two angle out of these = ${180}^{\circ }$
$\therefore$ Sum of other two angles will be =${360}^{\circ }-{180}^{\circ }={180}^{\circ }$
