Question

Diagonals of a quadrilateral bisect each other. If angle A=45°, then angle B =

Answer 1

Diagonal of a rhombus bisects each other and it has the property that it's opposite sides are equal and since it is a quadrilateral sum of all the four angles is 360°.

Therefore ,

2A+2B=360°

45+B=180°

So, B=135°
