Question

draw an equilateral triangle with perimeter 13cm​

Answer 1

Explanation:

We know that,

equilateral triangles have 3 equal sides

therefore, side of the given equilateral is 13/3 = 4.3 cm.

Steps to construct an equilateral triangle:

1. Draw a base AB of length 4.3 cm.
2. Take a measure of 4.3 cm in your compass and draw an arc placing the needle of compass on point B.
3. Similarly, draw an arc from point A as well such that it intersects the first arc, be sure that the measurement in the compass is not changed.
4. Mark the intersection of arcs as C. Join AC and BC to get an equilateral triangle.
