Question

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

Answer 1

In an equilateral triangle all the sides as well as well as angles are equal if one of its side is $6.2cm$ then ,

obviously all the sides are also equal and as we know that all the angles are also equal then

Let us take the angles be $x$

$x+x+x=180$ (angle sum property of a triangle)

Also,

$x+x+x=180$

$\Rightarrow 3x=180$

$\Rightarrow x=\frac{180}{3}={60}^0$

$\therefore x={60}^0$

Hence we get that the angle are ${60}^0$.
