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 and two angles of equal measure.

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°).

There are three special names given to triangles that tell how many sides (or angles) are equal. How to remember? Alphabetically they go 3, 2, none: Isosceles: means "equal legs", and we have two legs, right? Also i SOS celes has two equal "S ides" joined by an " O dd" side. Scalene: means "uneven" or "odd", so no equal sides. What Type of Angle?

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.

2024年12月17日 · 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

2023年8月3日 · 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.

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.

2025年2月24日 · 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.
