a right angle which is 90 degrees
right...Each corner of a square is called a "right angle" and measures 90 degrees with a protractor.a 90o angle, also called a right angle
A square is a square. It has 4 equal sides, and each forms a 90 degree angle.
A square has for sides joined to each other forming four vertices. It forms 90 degree angle at every vertex. Therefore there are 4 right angles in the rectangle.

Perpendicular intersection is like a 90 degree angle so anything that crosses and forms a 90 degree angle
A square has four angles. All of them are right angles of 90 degrees.
The segments of a square are perpendicular. Take the letter " T " for example. Where the bottom line connects the the top line forms a 90 degree angle, which makes them two lines perpendicular.
