Can a triangle have: All angles equal to $$60^{\circ}?$$
Justify your answer in each case.
Correct option is A. Yes
Given all the angles are equal to $$60^o$$.We know, by angle sum property, the sum of all the angles of a triangle is $$180^o$$.
Then, $$60^o+60^o+60^o=120^o+60^o=180^o$$.
Hence, it is possible for all the angles of a triangle to be equal to $$60^o$$.
That is, the statement is true and therefore, yes a triangle can have all angles equal to $$60^o$$.
