Diagonals of a quadrilateral `A B C D` bisect each other. If `/_A=45^0,` then `/_B=` `115^0` (b) `120^0` (c) `125^0` (d) `135^0`

Diagonals of a quadrilateral A B C D bisect each other. If /_A=45^0, then /_B= (a) 115^0 (b) 120^0 (c) 125^0 (d) 135^0

The diagonals A C\ a n d\ B D of a rectangle A B C D intersect each other at Pdot If /_A B D=50^0, then /_D P C= 70^0 (b) 90^0 (c) 80^0 (d) 100^0

The diagonals A C\ a n d\ B D of a rectangle A B C D intersect each other at Pdot If /_A B D=50^0, then /_D P C= 70^0 (b) 90^0 (c) 80^0 (d) 100^0

In Figure, If /_A B C=45^0, then /_A O C= (a) 45^0 (b) 60^0 (c) 75^0 (d) 90^0
