One of its interior will be 90 degrees.
also there will be a little box in the corner to show that it is a right angle.
right triangle
If one of the three interior angles is 90 degrees then it is a 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.
right triangle
Pythagoras's Theorem is used to determine if a triangle is a right triangle or not.
right triangle
The right angle is formed by the intersection of the triangle's "legs".
If one of the three interior angles is 90 degrees then it is a 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.
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.
