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.
Isosceles triangle - Wikipedia
In geometry, an isosceles triangle (/ aɪ ˈ s ɒ s ə l iː z /) 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.

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°).

2024年9月13日 · An isosceles triangle is a type of triangle in geometry that has two sides of equal length and the angles opposite those sides are also equal. This fundamental shape is frequently used in geometry problems due to its symmetrical properties, making it one of the core figures in Euclidean geometry.
