An isoceles is a type of triangle with two sides of equal length. Like all triangles an isoceles triangle has three interior angles.
3. every triangle have three sides
An isosceles triangle has two congruent sides.
It has to have at least 2 congruent angles and/or sides to be isosceles. Therefore, an equilateral angle would be isosceles.
Well since isosceles can only have two equal angles and two equal sides and a triangle has 3 angles and 3 sides it can really only have 1 line of symmetry.
two because isosceles triangles have two congruent sides
There are three primary types of triangle - the equilateral, where all three sides are equal in length - the isoceles, where only two sides are equal in length - and the scalene, where no sides are equal in length. The right triangle, where one angle is 90 degrees, is a special case of isoceles or scalene.
A scalene triangle has no equal sides.
Three equal sides in the form of an equilateral triangle and two equal sides in the form of an isosceles triangle
None!!!! EQUILATERAL TRiangle = 3 equal sides ISOSCELES Triangle = 2 equal; sides RIGHT ANGLED TRIANGLE = possible 2 equal sides. SCALENE Triangle = NO equal sides.
Every triangle has 3 sides but with a equilateral triangle all sides are equal
