Question

construct an equilateral triangle whose perimeter is 16.2 cm

Answer 1

As the perimeter is 16.2 cm and an equilateral triangle has three equal sides we get

Side lenght=

$16.2 \div 3$

5.4 cm

The steps to draw an equilateral triangle with length 5.4 cm are:

1. Draw a line BC = 5.4 cm

2. Using a compass, take radius 5.4 cm and using B as a centre draw an arc.

3. Taking the same radius and using C as a centre, cut the previous arc at A.

4. Join AB and AC

ABC is the required triangle
