The isosceles triangle side calculator will determine the lengths of an isosceles triangle if you give it the area, the height, the angles, or the perimeter.

Aug 1, 2025 · Calculator to find sides, perimeter, semiperimeter, area and altitudes of Isosceles Triangles. Given 2 unequal known sides you can find the unknowns of the triangle.

Isosceles triangle ... In geometry, an isosceles triangle (/ aɪˈsɒsəliːz /) is a triangle that has two sides of equal length and two angles of equal measure.

An isosceles triangle is a triangle that has at least two sides of equal length. Since the sides of a triangle correspond to its angles, this means that isosceles triangles also have two angles of …

In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle, and the point associated with …

We know that triangles are three-sided polygons and they are classified as equilateral, isosceles, and scalene, based on the length of their sides. In this article, we will learn about the definition …

Definition: This calculator computes the base angle (α), area, perimeter, leg length (a), and base length (b) of an isosceles triangle, given the vertex angle (β) and the height from the apex (h b).

Just enter any two known values, and the calculator intelligently applies trigonometric and geometric formulas to solve the rest with step-by-step precision. This calculator uses formulas …

To simplify calculations related to these triangles, our Isosceles Triangle Calculator allows you to quickly determine its height, area, and perimeter with just two inputs: base length and equal …
