45 degrees. they have to be the same angle, because they are opposite equal lengths, and when added together they must equal 90, so as to make the total of the angles 180.

What is a Right angled isosceles triangle?
A triangle with a 90 degree angle and two 45 degree angles.
Which triangle is not an isosceles triangle?
An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * Not true. An obtuse or right angled triangles can be isosceles. It depends on the sizes of the two smaller angles. An isosceles triangle has two equal angles so a triangle with angles of size [A, (180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees would be an obtuse angled isosceles triangle. A triangle with angles of size (90, 45, 45) degrees is a right angled isosceles triangle.
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.
What triangle has 1 right angle and can be isosceles?
A right angled isosceles triangle!
What is the name of A triangle with 2 acute angles which are equal and one right angle?
Right angled isosceles
Can an isosceles triangle have a right angle?
Yes, when it has a 90 degree and two 45 degree angles it is an isosceles right angled triangle.

What type of triangle has 100 degree angle and two 40 degree angles?
An obtuse angled isosceles triangle.
When does right-angle triangle have least hypotenuse?
When it is an isosceles right angled triangle: with angles that are 90-45-45.
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.

A right angled isosceles triangle!
What is the name of A triangle with 2 acute angles which are equal and one right angle?
Right angled isosceles
An angle not congruent to the base angles of an isosceles triangle?
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
How many right angles does a isosceles triangle have?
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.
Classify the triangle by its angles and by its sides?
All angles equal = all sides equal = equilateral. Two angles equal = two sides equal = isosceles. All angles different = all sides different = scalene. An isosceles or scalene triangle may be right-angled or obtuse-angled if one of its angles is a right angle or obtuse angle (respectively).
