Let’s see if we can put these properties to work and answer a few questions. So, in EVERY equilateral triangle, the angles are always 60°. This is because all angles in a triangle always add up to 180°and if you divide this amongst three angles, they have to each equal 60°. The angles, however, HAVE to all equal 60°. The sides can measure anything as long as they are all the same. When all angles are congruent, it is called equiangular. In the activity, children will have to sort triangles into categories depending on the size of the angles and the length of the sides.
