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

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.

An isosceles triangle is a triangle having two sides of equal length. Learn the definition, parts, types, properties, formulas, triangle games, and much more! Parents

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.

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.

Apr 12, 2025 · An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length . This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.

Apr 5, 2024 · Are you wondering what is an isosceles triangle? This short guide shares an instant answer as well as the isosceles triangle definition, an explanation of the isosceles triangle properties, and an explanation of the isosceles right triangle (also …

May 29, 2023 · An isosceles triangle is a type of triangle that has two sides of equal length. These equal sides are known as the legs of the triangle, and the third side is known as the base . The base angles of an isosceles triangle, which are the angles opposite the two equal sides, are themselves equal in measure .
