Well they might be but in all cases no. Acute angles just have to have an angle less than 90 degrees to be acute!

Right angle is 90degrees acute angle is less than 90 degrees
An equilateral triangle has the same length for each side, and the same angle for each vertex. All triangles have a mathematical property that states that the sum of all three angles in any triangle will equal 180 degrees. Since we know that all angles are the same, and there are three of them, each angle must be 60 degrees. An acute angle is one that is less than 90 degrees, and thus, each of the three angles are acute.
No. An acute angle is an angle smaller than 90 degrees. A right angle is an angle that is exactly 90 degrees
yes in fact every triangle has at least one acute angle
A 10 degree acute angle is the same as a 10 degree acute angle and so therefore they are both congruent.
