Practical Geometry - Class 7 Mathematics - MCQ Test 3 - Question 1

Which among the following is used to construct a triangle?

Detailed Solution for Practical Geometry - Class 7 Mathematics - MCQ Test 3 - Question 1

S.S.S. criterion can be used indirectly to construct a triangle given the lengths of its three sides.

Practical Geometry - Class 7 Mathematics - MCQ Test 3 - Question 2

In the given figure, find the measure of∠ROT, if PQ = QR and ∠QPR = 60°. 

Detailed Solution for Practical Geometry - Class 7 Mathematics - MCQ Test 3 - Question 2

ΔPQR is isosceles since PQ = QR. 

∴ ∠QPR = ∠QRP = 60°

∠RQT is the exterior angle of ΔPQR which is equal to the sum of interior opposite angles 

∠P and ∠R. Hence, 

∠RQT = 60°+60° = 120°
