Question

Can all the four angles of a quadrilateral be obtuse angles? Give reason for your answer

Answer 1

Nope because the sum of opposite angles should to 180 and the sum of two obtuse angles are more than 180

Answer 2

No, all the angels cannot be obtuse angles because the total angle =360 if all the 4 angles are obtuse the Thier sum would be

91+91+91+91=364
360 is not equal to 364
