Question

Mark the correct alternative in each of the following:
1. If all the three angles of a triangle are equal, then each
one of them is equal to​

Answer 1

each one is equal to another,

i.e. if the ∆ is equilateral then each ∆ is of 60°

Answer 2

$\sf\pink{ \underline{ \underline{Given:-}}}$

Three angles of a triangle are equal

$\sf\orange{ \underline{ \underline{To \: Find:-}}}$

One of the angle

$\sf \purple{\underline { \underline{Answer:-}}}$

Sum of all angles of triangle =180°

Let one angle is x

∵Three angles of a triangle are equal

x+x+x=180°

3x=180°

x=60°

So all angles of a triangle =60°.
