Question

Construct an equilateral triangle each of whose sides measures 6.2 cm. Measure each of its angles.

Answer 1

$\begin{array}{l}\text{Steps of construction:}\\ 1.\text{Draw AB of length 6}\text{.2 cm}\text{.}\\ \text{2}\text{. By taking the centres as A and B, draw equal arcs of 6}\text{.2 cm on the same side of AB, cutting each other at C}\text{.}\\ \text{3}\text{. Join AC and BC}\text{.}\\ \end{array}$

When we will measure angles of triangle using protractor then we find that all angles are equal to 60$°$
