Introduce the Equilateral Triangle Theorem (if a triangle is equilateral, then it is equiangular).
Introduce the Equiangular Triangle Theorem (if a triangle is equiangular, then it is equilateral).
Discuss how the interior angles of an equilateral triangle will always measure 60^{0.}
Provide examples that demonstrate how to use these theorems to solve for unknown variables and unknown side lengths and angle measurements.
This packet should help a learner seeking to understand the relationship between the sides and angles of an equilateral triangle.
This video introduces some of the properties of equilateral triangles.
This video introduces the equilateral and equiangular triangle theorems.
