An isosceles right triangle must have an angle that measures what?

An isosceles right triangle has an angle of 900 and two sides of equal length and two equal angles. Therefore other two angles must be 450.

Does an isosceles triangle have right angles?

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 a right triangle the same as an isosceles triangle?

No. They are usually different.An isosceles triangle has two equal angles and two equal adjacent sides. An isosceles triangle with three 60° angles is the equilateral triangle.Only one isosceles triangle, which has two 45° angles, includes a right angle and is called an isosceles right triangle.

Can a right triangle be isosceles?

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.

Why does the acute angles in an isosceles right triangle always measures 45 degrees?

The question lists three facts: "triangle", "right", and "isosceles". Each fact carries important information. -- "triangle" ... The three angles in any triangle always add up to 180 degrees -- "right" ... One angle in a right triangle must be a right angle = 90 degrees. That leaves the other 90 degrees for the other two angles to share. -- "isosceles" ... Two of the angles in an isosceles triangle are equal. If there are 90 degrees to share between them, then each of them is 45 degrees.

Is an isosceles triangle equal to a right triangle?

An isosceles triangle is a right triangle only when the other two interior angles are each 45o.

What are the measures of all the angles n an isosceles right triangle?

180 Two angles are 45 degrees and between them the third angle is 90 degrees.
