The Pythagorean Theorem Calculator is the essential tool for solving right triangles. Whether you need to find the length of the hypotenuse or one of the legs, this calculator applies the famous $a^2 + b^2 = c^2$ equation instantly. It’s perfect for checking homework, construction projects, or any scenario involving 90-degree angles. Features Two-Way…

  Among all the shapes in geometry, the Right Isosceles Triangle holds a unique place. It is the perfect bridge between a square and a triangle. Imagine checking a square tile and cutting it perfectly in half from one corner to the other—what you hold in your hand is a Right Isosceles Triangle. Because it…

  Whether you are estimating the amount of siding needed for a gable roof or helping a student visualize geometry, calculating the area of a right triangle is a fundamental skill. The beauty of a right triangle lies in its simplicity: it is exactly half of a rectangle. This relationship makes finding the space inside…

The Orthocenter is the point where the three altitudes of a triangle intersect. An altitude is a perpendicular line drawn from a vertex to the opposite side. The Orthocenter of Triangle Calculator automates the finding of this intersection point using slope and linear equation logic. Features Altitude Intersection: Solves for the crossing point of perpendicular…

  Finding the third side of a triangle is a classic problem that requires different methods depending on what you know. The Third Side of Triangle Calculator implements the Law of Cosines for general cases, the Pythagorean Theorem for right triangles, and the Triangle Inequality Theorem to find the possible range of a third side….

  The SSS (Side-Side-Side) Triangle Calculator is the fundamental solver for when you have measured all three boundary lengths of a triangle but know none of the angles. Using the powerful Law of Cosines, it reverse-engineers the shape to provide every missing angle, plus the area and perimeter. Features Complete Solution: Finds Angles A, B,…

  A Scalene Triangle has NO equal sides and NO equal angles. It is the most common ‘random’ triangle found in nature and surveying. The Scalene Triangle Calculator uses the powerful Heron’s Formula to calculate the Area directly from the three side lengths, without needing to know any angles or height. Features Heron’s Formula Engine:…

  When you know two sides and the angle pinned between them, you have a classic SAS (Side-Angle-Side) scenario. The SAS Triangle Calculator uses the Law of Cosines to bridge the gap, calculating the missing third side and the remaining two angles with ease. Features Included Angle Logic: specifically designed for the setup where the…

  For many, the word ‘trigonometry’ brings back memories of confusing equations and abstract symbols. But at its core, trigonometry is simply the study of triangles and how their side lengths relate to their angles. It is the mathematical bridge between linear measurement (how far) and angular measurement (what direction). Our Right Triangle Trigonometry Calculator…

  Geometry is efficient, precise, and everywhere around us—from the ramps we walk on to the roofs that shelter us. At the heart of many of these structures lies the right triangle, a three-sided polygon with one angle measuring exactly 90 degrees. Whether you are a student tackling homework, an architect designing a new home,…
