Geometric Twins Class 7 Short Question Answer

Question 1.

In ∆PQR of the figure, PQ = PR. Find the measures of ∠Q and ∠R.

Solution:

∠Q = 75°, ∠R = 75°

Question 2.

In the figure, ∆PQR is right-angled at P. U and T are the points on line QRF. If QP || ST and US || RP, find ∠S.

Solution:

∠S = 90°

Question 3.
