Two. Two acute angles in a right triangle.
In Euclidean geometry a right angle triangle has two acute angles. All others have three.
A triangle with 3 acute angles is simply called an acute triangle.An example is an equilateral triangle, which has three angles of 60° (acute).
An Acute Triangle
No, in fact no triangle can have two right angles. The sum of all interior angles of any triangle is 180 degrees. All triangles must have three angles. A right angle is 90 degrees. So if a triangle has two ninety degree angles, there would be no third angle. An acute triangle has all three angles less than 90 degrees. The most common acute triangle is the equilateral 60-60-60 degree triangle.
