It depends on what the formula is for: the area or perimeter or some other characteristic.

a triangle is not regular
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
If by regular, you're referring to a regular polygon which has all sides equal length, and all angles equal, then an equilateral triangle is a regular triangle. If you draw a scalene triangle or an isosceles triangle then it will not be equilateral.
Only when its an equilateral triangle then it is a regular polygon
Equilateral triangle, regular triangle.
