Right Triangle Calculator

Solve a right triangle from its two legs.

Hypotenuse 5

Area 6

Angle at a (°) 36.87

Formula: c = √(a²+b²); angle = atan(a/b)

Step-by-step with your numbers:

1. Values used:

2. Leg a = 3

3. Leg b = 4

5. Hypotenuse = 5

6. Area = 6

7. Angle at a = 36.87°

Did we solve your problem today?

Find the hypotenuse, area and angles of a right triangle.

The math behind it

Hypotenuse = √(a²+b²); area = ½ab; the angle opposite leg a is atan(a/b).

Legs 3, 4 → hypotenuse 5, area 6.

Other angle?

The two non-right angles add to 90°.
