Question

Construct an equilateral triangle of side 5.5 cm.

Answer 1

An equilateral triangle of side 5.5 cm has to be constructed. We know that all sides of an equilateral triangle are of equal length. Therefore, a triangle ABC has to be constructed with AB = BC = CA = 5.5 cm.

The steps of construction are as follows.

1) Draw a line segment BC of length 5.5 cm.

2) Taking point B as centre, draw an arc of 5.5 cm radius.

3) Taking point C as centre, draw an arc of 5.5 cm radius to meet the previous arc at point A.

4) Join A to B and C.

ABC is the required equilateral triangle.
