Our online tools will provide quick answers to your calculation and conversion needs. On this page, you can solve math problems involving right triangles. You can calculate angle, side (adjacent, opposite, hypotenuse) and area of any right-angled triangle and use it in real world to find height and distances.
You can use this calculator to solve for all kinds of everyday problems involving height and distance (trigonometry), 3-4-5 rule in construction to build square corners, angle of slope of properties and many more.
Formulas used for calculations on this page:
a2 + b2 = c2
sin(A) = a/c, cos(A) = b/c, tan(A) = a/b
sin(B) = b/c, cos(B) = a/c, tan(B) = b/a
Area = a*b/2, where a is height and b is base of the right triangle.
