Oh! Very clever! Now we have an equilateral triangle. Three sides of equal length andall the angles are 60 degrees. This is a scalene triangle. All the sides are different lengths and each angle ...

This means that this triangle is scalene. A scalene triangle has no sides that are congruent. Again, if the measurements were not labelled, you would still know it is a scalene triangle because ...

Properties of symmetry: - Students may notice symmetry in the isosceles and equilateral triangles and non-symmetry in the scalene triangles Informal recognition of these properties may be helpful in ...

It categorizes triangles into equilateral, isosceles, scalene, obtuse, right, and acute based on their sides and angles. The video also covers the concept of congruency, demonstrating how two ...
