90 degrees
90 degrees is always one of the three angles in a right triangle (say angle c)
The two other angles (a and b) depend on the lengths of the two sides ( say
A and B) that include the 90 degree angle and their sum will equal 90 degrees
(total = 180 degrees)
Angle c = 90
Angle a = x
Angle b = 90-x
x = arctan(A/B)

How do you find the measures of the angles in a right isosceles triangle?
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.
How do you find the hypotenuse of triangle?
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
Does a triangle has no right angles?
A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.
Number of obtuse angles in a right triangle?
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
Does a right angled triangle is one angle always a right angle?
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
