If one of the three interior angles is 90 degrees then it is a right triangle.
right triangle
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
It is formed by the diagonal of a rectangle

If a triangle has a right angle, it is a right triangle.
there will be a right angle in the triangle.
If one of the angles in a triangle is exactly 90 degrees, then it is a right-angle triangle.
Pythagoras's Theorem is used to determine if a triangle is a right triangle or not.

If one of the three interior angles is 90 degrees then it is a right triangle.
right triangle
The right angle is formed by the intersection of the triangle's "legs".
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
In a right triangle, the hypotenuse is the side of the triangle that is opposite the right angle formed by the other two legs.
It is formed by the diagonal of a rectangle
A right angle triangle is formed if you draw a line through it straight down from the pointed tip to the base.
