The two other angles are 45 degrees each.
The three angles of every triangle always add up to 180 degrees.
-- A right triangle is a triangle that has a right angle in it.
-- A right angle is 90 degrees.
-- That leaves 90 degrees for the other two angles in the right triangle.
-- If it happens to be isosceles, then the other two angles are equal.
-- Those must both be 45 degrees.

Do scalene triangles have three different angles?
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.
Why does the acute angles in an isosceles right triangle always measures 45 degrees?
The question lists three facts: "triangle", "right", and "isosceles". Each fact carries important information. -- "triangle" ... The three angles in any triangle always add up to 180 degrees -- "right" ... One angle in a right triangle must be a right angle = 90 degrees. That leaves the other 90 degrees for the other two angles to share. -- "isosceles" ... Two of the angles in an isosceles triangle are equal. If there are 90 degrees to share between them, then each of them is 45 degrees.
An isosceles right triangle must have an angle that measures what?
An isosceles right triangle has an angle of 900 and two sides of equal length and two equal angles. Therefore other two angles must be 450.
If a triangle has two congruent angles, then the triangle is?
isosceles
What triangle has one right angle and can be an isosceles?
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
