Oct 13, 2018 · An isosceles triangle is a type of triangle that has two sides that are the same length. The two marked sides are both the same length. The two angles opposite these two …

In the given isosceles triangle ABC, the two angles ∠B and ∠C, opposite to the equal sides AB and BC, are equal to each other. The sum of three angles of an isosceles triangle is always 180°.

The isosceles triangle calculator is the best choice if you are looking for a quick solution to your geometry problems. Find the isosceles triangle area, its perimeter, inradius, circumradius, …

The two equal angles at the base (opposite the legs) are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.

Use our isosceles triangle calculator to find any part of an isosceles triangle. Calculate any leg, angle, perimeter, or area of a triangle.

An isosceles right triangle is a triangle with 2 congruent sides and angles in which the non-congruent angle measures 90°. Because the sum of a triangle's interior angles is equal to …

The isosceles triangle theorem states that the angles opposite to the equal sides of an isosceles triangle are equal in measurement. So, in an isosceles triangle ABC where AB = AC, we have …
