equilateral have all equal sides.scalene have no equal sides.
It is a triangle whose 3 sides are equal in length and its 3 interior angles each measure 60 degrees
An equilateral triangle has three equal sides and three equal angles. Each angle is 60 degrees.
A triangle with 3 equal sides is an equilateral triangle. A triangle with 2 equal sides is an isosceles triangle. There is no such thing as a triangle with ONE equal side. Equal to what? If you wish to stretch it and say each side is (equal to itself only ) not equal to any others it is a scalene triangle.
It is an equilateral triangle
a equilateral triangle has 3 sides that each equal 15 cm
Two sides of an isosceles triangle are equal to each other.
a is one of the equal sides of the iscosceles triangle b is the base perimeter is a + a + b = 46cm a = b + 5cm subsitute a for b + 5cm in the perimeter equation b + 5cm + b + 5cm + b = 46cm This simplifies down to 3b + 10cm = 46cm subtract 10cm from both sides of the equation 3b + 10cm - 10cm = 46cm - 10cm 3b = 36cm Then divide each side of the equation by 3 3b ÷ 3 = 36cm ÷ 3 b = 12cm Subsitute b back into a = b +5cm a = 12cm + 5cm a = 17cm So you have 2 sided with the length of 17cm and the base with the length of 12cm
equilateral have all equal sides.scalene have no equal sides.
Not all. Only equilateral triangles have. Equilateral triangles have equal sides and 60 degrees on each corner of the triangle. Other triangle need not have equal sides.
By definition, an equilateral triangle, which is a triangle whose sides are equals and each of its angles has 60º.
They both have 3 sides but an isosceles triangle has two equal sides whereas an acute triangle with different acute angles has no equal sides and is said to be a scalene triangle, or an acute triangle with three equal acute angles (of 60° each) and three equal sides is called an equilateral triangle.

An equilateral triangle has three equal sides and three equal angles. Each angle is 60 degrees.

An equilateral triangle has three equal sides. The angles of an equilateral triangle measure 60 degrees each, but the sides can be any length.
