Yes because it has three equal sides.

All three angles inside an equilateral triangle are 60 degrees each.
a triangle is not regular
the angle in a rectangle is 90 degress angles in a equilateral triangle is 60 degree each. in this question they usually give you the triangle at an angle and give you what the angle is. so if you add them together they should all add to 90 degrees. so basically the trick is in what type of triangle it is.
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.
A scalene triangle is irregular. Only an equilateral triangle is regular.
that is a square, which would also be equiangular
A regular triangle is a equalateral triangle. A regular triangle is one for which all sides are congruent and all interior angles ---- are congruent ---- ---- ---- ----
