Determine whether the following regular polygon tessellates the plane. Explain.equilateral triangle

An equilateral triangle has three equal interior angles, so each measures 180° ÷ 3 = 60°. Six 60° angles fit around a point (6 × 60° = 360°), so copies of the triangle can cover the plane without gaps or overlaps. The correct choice is “yes; measure of interior angle = 60.”
