Question

in ∆ABC ,p is the mid point of BC ,Q is the mid point of AC and CT parallel to AB Find all angles of the triangle ABC​

Answer 1

Explanation:

To Prove :-

Construction :-

Draw PS parallel to BR to meet AC at S.

Proof :-

In Δ BCR, P is the mid-point of BC and PS is parallel to BR.

Where, S is the mid-point of CR

So, ----- (1)

Again, In Δ APS, Q is the mid-point of AP and QR is parallel to PS.

Where, R is the mid-point of AS.

So, ----- (2)

From equations (1) and (2),

We get, AR = RS = SC

∴

Further u can apply A+B+C =180
