The video tutorial explains the properties of equilateral, isosceles, and equiangular triangles. It highlights that in an equilateral triangle, all sides are equal, and in an equiangular triangle, all angles are equal, each measuring 60 degrees. The tutorial also covers the relationship between equal sides and angles in isosceles triangles.

What defines an equilateral triangle?

How do you find the remaining angles in an equilateral triangle if one angle is known?

Explain the relationship between the sides and angles in an isosceles triangle.

What is an equiangular triangle and how is it related to an equilateral triangle?

If one angle of an equiangular triangle is 60 degrees, what are the measures of the other angles?
