Question

A rectangle PQRS with sides PQ and RS of length 13cm and 20cm respectively.

Answer 1

Answer:

In a parallelogram, opposite angles are congruent.

∠XYZ = ∠XWZ = 135°

Also, WX || ZY

So, ∠YZW + ∠XWZ = 180° (Since, interior angles on the same side of the transversal are supplementary)

⇒∠YZW+135°=180°⇒∠YZW=45°

Now l(OY)= 5

we know that diagonals of a parallelogram bisect each other.

So, l(WY) = 2×OY=2×5=10 cm
