45 degrees.
They are: 45, 45 and 90 degrees
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
180 Two angles are 45 degrees and between them the third angle is 90 degrees.

If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
45, 45 and 90 degrees
180 Two angles are 45 degrees and between them the third angle is 90 degrees.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
50 degrees. 45 and 85 add up to 130 and in a triangle there are 180 degrees in total in a triangle. So subtract and you get 50 degrees.
80
No. The sum of the measures of the angles of a triangle must equal 180 degrees. 45+35+60=140, so these angles can't form a triangle.
An isosceles right angled triangle
A 45-45-90degree triangle is classified as an isosceles triangle.
