Answer 1

The equilateral triangle means all the sides of a triangle are equal.
 The steps of construction are as follows:
1.draw a straight line PQ of 15 cm.
2. at P draw an angle RPQ of 60 deg, at Q draw an angle SQP of 60 deg.
3. draw the angle bisectors of ∠RPQ and ∠SQP.
4. it intersects at point A.
5. draw the perpendicular bisector of PA and QA.
