Triangles Right
Calculate missing sides and angles of a right triangle using Pythagoras' theorem and trigonometry. Perfect for students, engineers, and designers online.
right triangle angle calculator
A right triangle calculator assists one in finding the missing sides or angles of a right triangle in a short time by using the Pythagorean formula and ratios of trigonometry. Enter sides one already known, or an angle, and the calculator puts the other sides and angles on your screen instantly.

Right Triangle Calculator is an internet-based resource that determines unknown sides and angles of a right triangle. One can enter two sides or one side and one angle and immediately obtain correct results with the help of the Pythagorean theorem and trigonometric ratios (sine, cosine, tangent). It finds the hypotenuse, base, height, and the remaining angles, and thus is useful when a student, engineer, architect, or even a designer requires an accurate right triangle measurement to solve math problems, construct, or design a project. The interface is easy to use, intuitive, and does not require any installation, and provides immediate results, with fewer errors in calculations made manually.
Work, Installation, Input to Output
Work:
- Accepts any two known values (sides or side + angle).
- Uses Pythagoras: \( c^{2}=a^{2}+b^{2} \)
- Uses trigonometry for angles: sin, cos, tan.
- Computes missing side(s) and angle(s) in degrees.
- Displays results instantly.
Installation:No installation required; works in any modern web browser.
Input:
- Any two sides or one side and one angle
Output:
- Hypotenuse
- Base and height
- Remaining angles
Testing and Final Adjustments
Test various sizes of triangles, even decimals. Pythagoras and trigonometry: Manually validate results. Some invalid input, such as negative sides or angles greater than 90 degrees, should be handled. The angles are to add up to 90 o. Rounds off decimals in the right way. Responsibility for phone and desktop test. Report immediate updates on changes to inputs. Present results in a clear and unitary manner. Optional: a little triangle diagram, which is shown moving graphically depending on the inputs.
