Take out a map of the U.S. Locate Arizona. Look at its borders with other states, and find the four right angles. These are the "Four Corners" states.
Assuming your question is what makes a right-angle, it is an angle of 90o .
A right triangle is one that has a right angle.
It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.
Right triangles have two acute angles, but that doesn't make them right. Having a right angle makes them right.
Three right angles, where one of the "arms" of the angle curves inwards which makes the angle appear less than a right angle.

Area = (Base x Height) / 2 For a right angle triangle Pythagoreas' Theorem states: a2 + b2 = c2 sum of angles = 180o For a non-right angle triangle: { the Sine Law states: a/Sin(A) = b/Sin(B) = c/Sin(C) for ease of explanation let abc be lengths of a non-right angle triangle. {a / Sin(angle where b meets c)} = {b / Sin(angle where c meets a)} = {c / Sin(angle where a meets b)} The Cosine Law states: (with respect to the above example) a2 = b2 + c2 - 2bc Cos(A) b2 = a2 + c2 - 2ac Cos(B) c2 = a2 + b2 - 2ab Cos(C) }
There is no specific name for such an angle.
A right triangle is one that has a right angle.
The corner. Where the floor meets a wall. Or the ceiling meets the wall. In the window sill. In a door way.
90 degrees
It is not and so the question makes no sense!
A total of 90 degrees makes up a right angle.

They are right angles
