It is 100 degrees. Or maybe just 90 degrees. Anyhow, one of it is right angle and the another one is the boiling point of water.

It's the angle formed by 2 perpendicular straight lines. We say 2 straight lines are perpendicular if the adjacent angles they form are equal. This angle is called a right angle. Like the angle formed by an horizontal and a vertical line.
By convention, the measure of a right angle is 90 degrees. Or pi/2 radians.

A right angle is the same as a 90 degree angle, three right angles make a right triangle; four right angles make a rectangle or square if all the sides are egual.

Right triangle is when one of the angle is 90 degree in a triangle.
It is when we join A and C we get a triangle with one angle 90 degree.
