The definition of a right angle is an angle measuring 90 degrees. You don't have to calculate anything.
A right angle is always 90 degrees. That is 1/4 of a complete circle, which would be 360 degrees.
Height will be h=base*tan(angle).

Right angles are always 90 degrees. There is no need to calculate this; an angle is either 90 degrees or it is not. The following inline function is all you really need: inline const bool IsRightAngle(double angle) { return(angle==90.0); }
It depends what you need to calculate. There are various formulas for this. It is a branch of mathematics called trigonometry.

if you have any two sides, you can calculate either of the (non right angle) angles. if you have a (non right angle) angle and one side, you can calculate any other side. you will need either tables, or a scientific calculator with sin / cosine / tangent function

By using the tangent ratio of: opposite/tangent angle = adjacent which is the base
With Pythagoras' theorem or trigonometry depending on the information you are given.
If it's a right angle triangle then:- a2+b2 = c2 where 'c' is the hypotenuse and the square root of this is the length of the hypotenuse when 'a' and 'b' are the other sides of the right angle triangle.
