ANSWER :

Equilateral Triangle

Step-by-step explanation:

The reason why this is so is that polygons of one type

meet at a point, the sum of the interior angles is

360 degrees.

Hopefully it helps!

An equilateral triangle is the regular polygon that can completely tessellate a plane, which means that it can fill a two-dimensional space without any gaps or overlaps. This is because the angles and sides of an equilateral triangle are equal, which allows it to fit together perfectly with itself. A regular decagon, an obtuse scalene triangle, and a regular nonagon cannot tessellate a plane without gaps or overlaps.
