The other two angles are "acute angles".
The sum of the angles in a triangle MUST add up to 180 degrees.
If 90 of the degrees are used up in the right angle (the very definition of a right angle), then that leave 90 degrees to be divided up between the two remaining angles. Thus, they would both be LESS THAN 90 degrees (the very definition of an acute angle.)

How many angles does a right triangle have?
A right triangle has only one right angle (a 90 degree angle), by definition. The sum of the other two angles equals 90 degrees, so the sum of all three angles is 180 degrees. Every triangle, right triangle or not, has three angles whose sum is 180 degrees.A right angle triangle has only 1 right angle which measures 90 degrees
What kind of triangle is a triangle with the angles 18 90 and 72 degrees?
The triangle contains a 90 degree angle, making it a right-angled triangle.
What Kind of name is a triangle?
