Question
Class 7MathematicsPractical Geometry

There are four options, out of which one is correct. Choose the correct one:

(i) A triangle can be constructed with the given measurement.

(a) 1.5 cm, 3.5 cm, 4.5 cm

(b) 6.5 cm, 7.5 cm, 15 cm

(c) 3.2 cm, 2.3 cm, 5.5 cm

(d) 2 cm, 3 cm, 6 cm

(ii) (a) m∠P = 40°, m∠Q = 60°, AQ = 4 cm

(b) m∠B = 90°, m∠C = 120° , AC = 6.5 cm

(c) m∠L = 150°, m∠N = 70°, MN = 3.5 cm

(d) m∠P = 105°, m∠Q = 80°, PQ = 3 cm

Verified Answer

(i) Option (a) is possible to construct.

1.5 cm + 3.5 cm > 4.5 cm

(ii) Option (a) is correct.

m∠P + m∠Q = 40° + 60° = 100° < 180°
