No.
The three angles in a triangle, in plane Euclidean geometry, must add to 180 degrees.
Acute angles are less than 90 degrees.
Therefore you may have a triangle with three angles which are 60 degrees for instance.

A right triangle has an acute and right angle.
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
