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).

An isosceles right triangle is always a 45 45 90 triangle?

Not always because it could be a 50 50 80 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.


Can a isosceles be a right triangle?

No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.

What are the angle measurements for an isosceles right triangle?

An isosceles triangle has two sides and angles that are equal, causing it to have exactly a line of symmetry through it. A right triangle has one angle that is 90 degrees. An isosceles right triangle will always have one angle that is 90 degrees, while the other two angles will be 45 degrees.

Not normally but if it has angles of 90, 45 and 45 degrees it is then both a right angle and an isosceles triangle


Is an isosceles triangle a right triangle?

It can be because it depends on the triangle's angles. For example, if the triangle has 2 equal sides and a right angle it could be a isosceles and a right triangle.
