An isosceles triangle is a type of triangle that has any two sides equal in length. The two angles of an isosceles triangle, opposite to equal sides, are equal in measure. In geometry, triangle is a three-sided polygon that is classified into three categories based on its sides, such as: Scalene triangle (All three sides are unequal)
In geometry, an isosceles triangle ( / aɪˈsɒsəliːz /) is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case .
In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal. 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.
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 of an isosceles triangle, its properties, and some isosceles triangle examples.
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°).
An isosceles triangle is a triangle that has (at least) two equal side lengths. If all three side lengths are equal, the triangle is also equilateral. Isosceles triangles are very helpful in determining unknown angles.
Aug 3, 2023 · Definition. Isosceles triangle is a figure where two sides are of equal length and two angles are equal. Isosceles Triangle. Properties of an Isosceles Triangle. Two equal (congruent) sides; in ∆ABC, AB and AC are two congruent sides. One line of symmetry. The two angles opposite to the equal sides are equal (isosceles triangle base angle theorem).
4 days ago · An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length b and the remaining side has length a. This property is equivalent to two angles of the triangle being equal.
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.
An isosceles triangle is a triangle that has at least two congruent sides. The congruent sides of the isosceles triangle are called the legs . The other side is called the base .
