In an isosceles triangle, two angles, and therefore sides (Base Angle Theorem), are congruent. This does not mean that all isosceles triangles are also right triangles - there is only one (45, 45, 90 triangle).

Does an isosceles triangle have a right angle?
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
Is an isosceles right triangle always 45-45-90 triangle?
Yes
What does a right triangle and an isosceles triangle have in common?
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
True or false An isosceles right triangle is always a 45-45-90 triangle?
True
Is a right triangle an isosceles triangle?
It can be. If two of the sides of a right triangle are the same length then it is an isosceles triangle
Is a right triangle always an isosceles triangle?
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
Does an isosceles triangle have a right angle?

Is an isosceles triangle always congruent to a right triangle?
Not all the time but it can happen
Is an isosceles right triangle always 45-45-90 triangle?
Yes
Is a right triangle an equilateral triangle always sometimes or never?
Never but an isosceles triangle can sometimes be a right angle triangle
Is the isosceles triangle is always a right triangle?
It usually is a right angle that represents an isosceles triangle but there are some cases that the right and left side are equal and the base is the one with an unequal length.
What does a right triangle and an isosceles triangle have in common?
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
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.
Are right triangles always isosceles?
No. For example a 3, 4, 5 cm triangle is right angled but not isosceles.
How many degrees are in a right isosceles triangle?
The three angles inside EVERY triangle ALWAYS add up to 180 degrees.In an isosceles right triangle, the angles are 45°, 45°, and 90°.
True or false An isosceles right triangle is always a 45-45-90 triangle?
True
