An isosceles triangle is a triangle that has any two sides equal in length and angles opposite to equal sides are equal in measure. The perimeter of an isosceles triangle is 2a + b. Learn properties at BYJU’S.

In geometry, an isosceles triangle (/ aɪ ˈ s ɒ s ə l iː z /) is a triangle that has two sides of equal length or two angles of equal measure.

What Is an Isosceles Triangle? A triangle with two sides of equal length is an isosceles triangle. Many things in the world have the shape of an isosceles triangle. Some popular examples of these triangles in real life are: Source: Parts of an isosceles triangle. 1. Legs: The two equal sides of an isosceles triangle are called “legs.”

Dec 17, 2024 · An isosceles triangle is a type of triangle in geometry that has at leasttwo sides of equal length. T he angles opposite these sides are also equal. Suppose we have any triangle PQR then it is an isosceles triangle if any one of the given conditions is true: PR = QR; ∠P = ∠Q

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 180°, the remaining two angles in an isosceles right triangle measure 45° (90 + 45 + 45 = 180°).

Aug 3, 2023 · Isosceles triangle is a figure where two sides are of equal length and two angles are equal. The two angles opposite to the equal sides are equal (isosceles triangle base angle theorem). In ∆ABC, since AB = AC, ∠ABC = ∠ACB.

Isosceles triangles are those triangles that have two sides of equal measure. We know that triangles are three-sided polygons and they are classified as equilateral, isosceles, and scalene, based on the length of their sides.

A triangle having two equal sides is known as an isosceles triangle. The two equal sides are called legs, and the third side is known as the base of the isosceles triangle. The angle between the legs is called the vertex angle, and the two angles adjacent to …

What is an isosceles triangle? An isosceles triangle is a unique type of triangle because it has two equal (congruent) sides and two equal (congruent) angles. Properties of an isosceles triangle: Two sides of equal length. Two equal angles. The dashes on the sides and the angles of the triangle mean they are equal in measure or congruent.

What is an isosceles triangle? An isosceles triangle is a type of triangle with the following properties. Two sides of equal length. Two equal angles. The two sides that are opposite the two equal base angles are equal in length. The third side which is unequal is sometimes known as the base of the triangle.
