Question

Construct ∆ ABC, in which BC =3.2cm, | ABC=45° and perimeter of ∆ ABC is10cm

​

Answer 1

STEPS OF CONSTRUCTION

• Draw the line BC of 3.2cm

• Draw angle B of 45°

• With the centre B draw an arc of 10 cm (BD)

• Now join point C to point D

• Draw a bisector of line CD

• The point at which the bisector of line CD will intersect the line BD will be the point A

• Join the points

• ∆ ABC is the desired ∆
