A right triangle is a geometrical shape in which one of its angle is exactly 90 degrees and hence it is named as right angled triangle. It has a base side, a hypotenuse and height of the triangle. We know that hypotenuse = √(Base^2 + Height^2). This right triangle calculator helps you to calculate angle and sides of a triangle with the other known values. You can select the angle and side you need to calculate and enter the other needed values.
The formulae (formula) for calculating angle and sides of a triangle can be easily remembered using the sentence -Old Harry And His Old Aunt.
A right triangle with 5 cm as base and 10 cm as height, will have an hypotenuse value of
= √(5^2 + 10^2)
= √(25 + 100)
= 11.18 cm
Substituting the hypotenuse and opposite side values in the Sin q formula, we have
Sin q = 10 / 11.18
= 63.43 degrees
