All triangles are polygons, having three straight-line sides. However, a right triangle is not a "regular polygon" because the three side lengths and interior angles cannot be the same (the right angle takes up 90 degrees of the total 180). An equilateral triangle is a regular polygon.
What else can I help you with?
Quadrilaterals are polygons that have three sides?
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
What shapes have no right angels and no equal sides?
