Isosceles triangle - Wikipedia
In geometry, an isosceles triangle (/ aɪˈsɒsəliːz /) is a triangle that has two sides of equal length or two angles of equal measure. 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.

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 triangle - Math Steps, Examples & Questions
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.
