Description

📐 Right Triangle Calculator – Solve Sides, Angles & Area

The Right Triangle Calculator helps you find missing sides, angles, perimeter, and area of a right-angled triangle. Using the Pythagorean Theorem and basic trigonometry, it provides step-by-step solutions for geometry and real-life applications.

📘 What It Calculates:

  • ✅ Missing side using Pythagorean Theorem

  • ✅ Angles using sine, cosine, and tangent

  • ✅ Perimeter and area of the triangle

  • ✅ Step-by-step geometry and trig solutions

💡 Features:

  • Input any combination of sides/angles

  • Automatic calculation of missing values

  • Works for simple and complex problems

  • Helpful in geometry, physics, and design

👤 Who Should Use This:

  • 📌 Students studying geometry & trigonometry

  • 📌 Teachers & tutors explaining right triangles

  • 📌 Engineers, architects, and designers

  • 📌 Anyone solving practical right-triangle problems

✅ Pro Tip:

  • Always identify the hypotenuse (longest side, opposite 90°).

  • Use trig ratios for angles:

    • sin⁡θ=oppositehypotenuse\sin \theta = \frac{\text{opposite}}{\text{hypotenuse}}sinθ=hypotenuseopposite​

    • cos⁡θ=adjacenthypotenuse\cos \theta = \frac{\text{adjacent}}{\text{hypotenuse}}cosθ=hypotenuseadjacent​

    • tan⁡θ=oppositeadjacent\tan \theta = \frac{\text{opposite}}{\text{adjacent}}tanθ=adjacentopposite​

🔗 Related Tools:

A right triangle has one angle equal to 90°, with the side opposite this angle called the hypotenuse.

They follow the Pythagorean Theorem: 𝑎 2 + 𝑏 2 = 𝑐 2 a 2 +b 2 =c 2 , where 𝑐 c is the hypotenuse.

Sine, cosine, and tangent are defined using side ratios: sin ⁡ = 𝑜 ℎ , cos ⁡ = 𝑎 ℎ , tan ⁡ = 𝑜 𝑎 sin= h o ​ ,cos= h a ​ ,tan= a o ​ .
