Your question contains the answer. It is a 'right' triangle.
A right triangle contains one 90 degree angle and the other angles must add to 90 because the sum of the angles in a triangle is 180 degrees.
A "right" triangle, so called because it contains a "right angle".
If a triangle has a right angle, it is a right triangle.
yes it is it is a triangle with a right angle in it
A right triangle is a triangle that contains a 90 degree angle, an obtuse triangle contains an angle that is from 91 degrees to 179 degrees.
A right triangle contains one 90 degree angle.
That's simply called a right triangle.

A right Iscolese
A right-angle triangle.
right triangle. pretty easy! lol. if it makes a right angle it should be a right triangle. if it is acute. it is an acute triangle, and the same with obtuse. its all simple to remember
A right angle triangle
A right angle triangle contains a 90 degree angle and 2 acute angles and all of the 3 angles add up to 180 degrees.
Right = 90 degrees, acute = less than 90 degrees, obtuse = over 90, but less than 180 degrees. (between 180 and 360 is called "reflex".) A right triangle contains one right angle; an obtuse triangle contains one obtuse angle; and an acute triangle contains only acute angles.
