By the properties of triangles, if all the sides of a triangle are equal, then the each of the angle of the triangle will also be equal.

By the question,

All sides of the triangle are equal.

∴ All angles of the triangle are also equal.

Let each angle of the equilateral triangle be x°. We know that the sum of all angles of a triangle is 360°.

x° + x° + x° = 360°

→ 3x° = 360°

→ x° = (360 ÷ 3 )°

∴ x° = 60°

Thus, all angles of the triangle measure 60° which is an acute angle (lying between 0° and 90°.)

Obtuse angles are those which lie between 90° and 180°.

Thus, when all sides are equal in a triangle, its angles measure 60° each. This implies that all angles are acute angles and not obtuse angles.

Thus, the statement p is false.
