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)
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.
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.
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.
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
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.

A triangle can never have three right angles
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.
You do not need to, if you have a right triangle that angle is 90* so the other 2 angles are 45* apiece. That is actually only partially accurate. There can be a right angled triangle with sides of 2-3-5. 5 being the hypotenuse in which the triangle's angles will not be 90-45-45 but 90-33.69-56.31. To find the angles of a right triangle, you will need to know the length of the sides. With the length of all three sides, you will need to utilize sine, cosine, and tangent to find the angles.
A right angle triangle has a 90 degree angle with two acute angles and the 3 interior angles add up to 180 degrees
An obtuse triangle can have no right angles, and has two equal angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
square has 4 right angles and triangle has no right angles
