A corner of 90 degrees is a right angle
Two angles are Adjacent if they have a common side and a common vertex (corner point) and don't overlap.
right angle
The hypotenuse is the longest side on a right triangle. It is the side that is opposite (directly across from and facing) the 90-degree angle. If your drawing shows a 90-degree angle by labeling it with a small corner (box), then the point of the corner always points toward the side that is the hypotenuse.

When you point to a corner of a table, you'll see the intersection of two sides, forming a right angle. This corner is where the edges meet and create a distinct point.

verticies are a point where two lines cross. Like a corner or an angle.
A square corner is a 90° angle which is called a "Right angle".
In math, a vertex is the point in an angle of which the two rays originate. You know that little dot that's at the "corner" of an angle? Yep, that's the vertex.
