An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
A right angled isosceles 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.
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.
