Enter the values you know and instantly get every missing side, angle, area and perimeter, complete with a clear step-by-step solution. No guessing and no messy formulas by hand — just tap, type and solve.

From a simple right triangle to a full oblique triangle, this all-in-one triangle solver and trigonometry calculator handles them all. Whether you are a student working through geometry homework, a teacher preparing a lesson, or a carpenter, engineer, machinist or DIY builder measuring on the job, it turns tricky trigonometry into a few quick taps.

► SOLVE ANY TRIANGLE

• Right triangle solver powered by the Pythagorean theorem (a² + b² = c²)
• Oblique, scalene, isosceles, equilateral and obtuse triangles
• Enter any valid 2–3 values — SSS, SAS, ASA or AAS — and get everything else
• Handles the tricky ambiguous case (SSA) and shows every possible triangle
• Instantly finds sides, angles, hypotenuse, area, perimeter and all three heights

► SEE EVERY STEP, NOT JUST THE ANSWER

• Clear, step-by-step solutions using Pythagoras, the sine rule and the cosine rule
• Understand the exact formula and working behind every single result
• Perfect for learning, revising and checking your homework with confidence

► BUILT FOR REAL, EVERYDAY USE

• Tap any side or angle right on the triangle diagram and start typing
• Fast, purpose-built keypad — no fiddly system keyboard getting in the way
• Live guidance shows exactly how many values you still need to enter
• Switch instantly between degrees, radians and DMS (degrees-minutes-seconds)
• Choose your own decimal precision, up to 10 places — never any forced rounding
• Metric and imperial units supported
• Full calculation history, so you can revisit earlier answers any time

► POWERFUL GEOMETRY TOOLS

• Circumcircle and incircle diameter calculators
• Regular polygon tools for triangle, square, pentagon, hexagon and octagon
• Ideal for machining, PCD (pitch circle diameter) and workshop layout work

► HANDY EXTRAS

• Similarity and Thales mode — find the height of a tree, pole or building from its shadow
• Solve from a photo — snap a printed problem, read off the values and get your answer
• Automatic right-angle detection with clear, colour-coded diagrams
• Save, review and share your results in seconds

► LEARN AND COMPETE

• Fun practice quizzes to sharpen your geometry and trigonometry skills
• Instant feedback with a clear explanation for every question
• On-device leaderboard with Diamond, Gold and Silver tiers to keep you motivated
