A right angle triangle
A right-angle is a 90 degree angleA right triangle has one, and a 90-degree angle isone.
Yes, the definition of a right triangle is that it has a 90 degree angle
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
right angle=90 degrees and a right triangle has one side of it that forms a 90 degree angle...as for the naming "right" don't know but it refers to 90 degree angle
A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
