Question

Construct ∆ABC in which BC = 6 cm, angel B = 30° and AB - AC = 3 cm.

Answer 1

Given : BC=6 cm   angle B=30°   AB-AC = 3 cm.

To Find : Construct triangle

Solution:

Step 1 : Draw a line segment BC of length 6 cm.

Step 2 : Draw an angle of 30° at point B on BC using protractor

Step 3 : Draw Ray BP

Step 4 :  From B take BX = 3 cm      

Step 5 : Join CX

Step 6 : Draw perpendicular bisector of CX  intersect ray BP at A

 Step 7 : Join A to C
