Answer 1

Constructed a triangle ABC

Steps of construction :

• Draw BC 6.5 cm long

• construct a angle of 60° with compass at B and extend the arm of angle.

• Cut an arc at 1.5cm on the

  extended arm of angle B & mark

   this point as D

• Join CD

•Draw perpendicular bisector of CD and let it intersect the extended arm of angle B

• Mark the point of intersection as A

• Required triangle is ready.
