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.
Pythagoras Theroem: a2 + b2 = c2Where a and b form a right angle and c is the hypotenus (longest side of a right angle triangle)=> 102 + 102 = c2{calculate the powers}=> 200 = c2{sqare root both sides}=> c = sqrt(200)c = sqrt(200) or 10*sqrt(2)
