A triangle is scalene if all of its three sides are different. If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral.
You can identify the types of triangles by measuring their sides and angles. An equilateral triangle has three equal sides, and three angles that all equal 60 degrees. An isosceles triangle Has two equal sides and one smaller side, with two angles that are larger than the third. A scalene triangle has three different sides and three different angles.
