Question

2. Construct APQR in which QR = 8 cm, ZB = 60° and AB --AC=3.5 cm ​

Answer 1

Step-by-step explanation:

Construct a triangle ABC in which BC = 8cm, ∠B = 45° and AB - AC = 3.5 cm

i) Draw base BC = 8cm, and at point, B make an angle CBX of 45° using a protractor.

ii) With B as center and radius BD = 3.5 cm, draw an arc to intersect ray BX at D.

iii) Join DC.

iv) Let's construct a perpendicular bisector of DC. With D and C as the center and radius greater than half of DC, draw arcs above and below the line DC to intersect ray BX at A.

v) Join AC.

ABC is the required triangle.

Verification:

On measuring we see that,

BC = 8cm, ∠B = 45° and AB - AC = 3.5 cm
