Question

In a rectangle KLMN, KM = 16 cm, KM and MN intersect at the point O. Find the length of ON.

Answer 1

Answer:

In parallelogram KLMN, ∠K=60

∘

[Given]

⇒ ∠K=∠M [Opposite angles of parallelogram are equal]

⇒ So, ∠K=∠M=60

∘

---- ( 1 )

⇒ ∠K+∠N=180

∘

[Sum of adjacent angles of parallelogram is supplementary]

⇒ 60

∘

+∠N=180

∘

∴ ∠N=120

∘

⇒ ∠N=∠L [Opposite angles of parallelogram are equal]

⇒ So, ∠N=∠L=120

∘

---- ( 2 )

From ( 1 ) and ( 2 ) we get,

∠K=60

∘

,∠L=120

∘

,∠M=60

∘

and∠N=120

∘

.
