Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles:
Scalene Triangle. Here we will learn about scalene triangles, including what a scalene triangle is and how to solve problems involving their sides and their angles. There are also scalene triangles worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
Discover the different types of triangles and find out the difference between an equilateral, scalene, isosceles and right-angled triangle in this KS2 guide.
A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees. Thus, it meets the angle sum property of the triangle.

A scalene triangle is defined as a three-sided polygon whose side lengths and angles are all different. To identify if a triangle is scalene, check whether it has any congruent sides or angles; if it does, it is not a scalene triangle; if it doesn't, it is a scalene triangle.
A scalene triangle is a triangle with all three sides of different lengths. In a scalene triangle, there are no equal side lengths and no equal angle measurements, which means the sides and angles are not congruent. Properties of a scalene triangle: No equal sides. No equal angles.
To classify a triangle as scalene, you can compare the lengths of the three sides. If they are all different, you have a scalene triangle. Alternatively, you can also look at the angles and check if they are all different. If all three angles are different, the triangle is scalene.
