## What is Right Calculator?

Solve any right triangle in seconds — no formulas, no calculator gymnastics.

Right Triangle Calculator does the trigonometry for you. Enter any two values — two sides, a side and an angle — and it instantly computes everything else: the missing sides, both angles, and the hypotenuse. It's built for people who measure in the real world, so you can type the way you actually work: feet and inches, fractions, or metric.

Whether you're framing a wall, cutting a rafter, laying out stairs, building a deck, or checking homework, the answer is one tap away.

REAL-WORLD MEASUREMENTS
• Mix feet, inches, and fractions — type "5 ft 3/8 in" directly
• Work in metric too — meters and centimeters
• Set fraction precision from whole numbers down to 1/64"
• Control decimal places for clean, readable results

SMART TRIANGLE SOLVER
• Enter any 2 of 5 values (sides a, b, c or angles A, B)
• Side c is always the hypotenuse, angle C is locked at 90°
• Automatic conflict handling — change your mind and it keeps up
• Powered by the Pythagorean theorem and trig, done instantly

SEE IT, DON'T JUST SOLVE IT
• Live diagram redraws as you type
• Rotate the triangle to match your layout
• Clean, labeled sides and angles you can actually read

ARC & CHORD MODE
• Switch to curves to solve chord, arc length, and segment height
• Perfect for woodworking, masonry, and curved layouts

MADE YOUR WAY
• Choose label color, label size, and decimal precision
• Optional tap sounds
• Fast, offline, and distraction-free

PERFECT FOR
Carpenters • framers • woodworkers • DIY builders • roofers • machinists • students • teachers • engineers • anyone who needs a fast right-angle answer.

Just measure, tap, and build.
