Yes all equilaterals can tessalate.This is because all the sides are equal and all the shapes can fit in properly.
Equilaterals
All sides are equal in lengths
A rhombus, square , paralellogram ,rectangle, and trapezoid

There can be two equilateral triangles with a side length of 7 cm: one on either side of the given line.
Squares are equilaterals (same length on every side) Rectangles could be called parallelograms but the parallel lines are the same. It's hard to explain but I could show you. _______________ | | |______________| equal on parallel sides.
Equilateral triangle * * * * * Why? Draw an arc, greater than half the distance of the line segment, from one of the end points. Another arc, using the same radius from the other end. Jion the two points where the arcs intersect - one on each side of the line. At best you get two isosceles triangles if yu join up other lines (which is not required), but certainly no equilaterals! ******* because it's APEX and it's stupid in ways you can't understand
