Right angled triangle.
A right-angled triangle is one which has, as one of the angles, an angle of exactly 90 degrees.
It is a triangle with one right angled vertex.
Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.
A right angled scalene triangle
angles that measure 90 degrees.
An isosceles right-angled triangle
Absolutely not, not ever, nohow! An equilateral triangle has three angles of 60 degrees, a right-angled triangle must have one of 90 degrees.
It is a right triangle or right-angled triangle. The right-angle is 90 degrees.
One angle (corner) must to 90 degrees.
They are: 90 degrees, 45 degrees and 45 degrees
its a triangle * * * * * No, it an obtuse triangle is not a right angle triangle. An obtuse angled triangle has one angle which is greater than 90 degrees and the other two are acute. In a right angled triangle, the largest angle is 90 degrees while the other two are acute. So one cannot be the other.
