Question

All the equilateral triangle present in the universe are

• A. Congruent
• B. Equiangular
• C. Acute angled triangle
• D. $\left(b\right)$ and $\left(c\right)$ both

Answer 1

The correct option is D $\left(b\right)$ and $\left(c\right)$ both

We know all the equilateral triangles have each angle to be ${60}^o$ and also we know ${60}^o<{90}^o$ is an acute angle.
hence every equilateral triangle is equiangular but not necessarily congruent as every equilateral triangle cannot have same side.
here also we can see that both the triangles have angles as ${60}^o$ but sides are not equal so are equiangular but not congruent.
