Question

two angles of quadrilaterals when a taker together make a two right angles find the sum of 2 angles

Answer 1

The two angle of quadrilateral are 360
so we have to make two Right angles

360÷2 =180 so we have to do 360-180= 180

Answer 2

Let the angles be a,b,c,d of the quadrilatral.
Now,
a + b = 90*
We know that sum of all the angles of a quadrilateral is 360*,
therefore,
c + d= 360* -( a + b)
=> c + d = 360 - 180*
=> c+ d = 180*......Ans
