For all triangles, right-angled included, it is the multiplication of the base length times the perpendicular height x half.

The area of a right angle is nothing bro, if you mean the area of a right angle triangle then uts simple formula is : 1/2×Base×Height(Perpendicular of the right angled triangle) Alternative method: Heron's formula!
It is the longest side in a right-angled triangle. You can find it by squaring and adding together the two shorter sides and when you get the answer, find the square root of the number.
To find the sine ratio of a right-angled triangle divide the opposite by the hypotenuse. For example: 4/5 = 0.8 units and sine-1(0.8) = 53.13010235 degrees.
