Question

10 Diagonals of a rectangle XYZW intersect each other at point P. If l (ZP) =8.5 cm, then find l (YW).​

Answer 1

Answer:

R.E.F.Image.

In a parallelogram, diagonal bisect each other 

∴OY=OW=5cm

∠XYZ+∠YZW=180∘ [∴ interior angles]

135∘+∠YZW=180∘

∠YZW=45∘

In a parallelogram, opposite angles are equal

∠XYZ=∠XWZ=135∘

and OY = 5 cm then WY = OY + OW

5+5=10cm [opposite diagonal]
