Given data:

The given triangle.

As all the sides of the triangle are equal, it means all the angles are equal. The expression for the angle sum property of the triiangle is,


\begin{gathered} x+x+x=180^(\circ) \\ 3x=180^(\circ) \\ x=60^(\circ) \end{gathered}

In the given triangle each angle is 60 degree, so it is an acute angle triangle.

Thus, the given triangle is an acute angle triangle, so first option is correct.

15)

The all sides and all angles of the triangle are equal.

Thus, the given triange is an equilateral triangle, so third option is correct.
