Isosceles triangle - Wikipedia Isosceles triangles have been used as decoration from even earlier times, and appear frequently in architecture and design, for instance in the pediments and gables of buildings The two equal sides are called the legs and the third side is called the base of the triangle
Isosceles triangle - Math. net 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°)
Isosceles Triangle -- from Wolfram MathWorld An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal Another special case of an isosceles triangle is the isosceles right triangle
Properties of Isosceles Triangles | Brilliant Math Science Wiki Because angles opposite equal sides are themselves equal, an isosceles triangle has two equal angles (the ones opposite the two equal sides) Thus, given two equal sides and a single angle, the entire structure of the triangle can be determined
Properties of Isosceles Triangle Explained with Examples An isosceles triangle is a triangle with at least two sides of equal length These equal sides are called the legs, and the angle between them is the vertex angle or apex angle
Isosceles triangle - math word definition - Math Open Reference Isosceles Triangle A triangle which has two of its sides equal in length Try this Drag the orange dots on each vertex to reshape the triangle Notice it always remains an isosceles triangle, the sides AB and AC always remain equal in length
