Question

Construct ABC such, that BC 4.8 m 40 , c90

Answer 1

1. Draw BC=4.8 cm.

2. Construct ∠B=30 ∘ .

3. Cut off line segment BD=12 cm on the 30 ∘ line. Join C−D,

4. Draw a perpendicular bisector of CD to intersect BD at A.

5. Join A−C.6. ABC is the required triangle.

Answer 2

1 .Draw a seg BC of 4.8 cm

2. Place your protractor at point B and draw a 40° angle

3. therefore∆ABC is the required triangle
