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.

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
