All of them can be used.
Any triangle or quadrilateral will tessellate. There are 15 classes of irregular convex pentagons which will tessellate. Regular hexagons and 32 classes of irregular convex hexagons will tessellate. There are also concave pentagonal and hexagonal shapes which will tessellate.
It could be a triangle, a quadrilateral, a pentagon, a hexagon or even an octagon if they are two concave quadrilaterals.
A circle, ellipse, and also a triangle, pentagon, hexagon etc - in fact all polygons other than quadrilaterals.

a 2d shape A two dimensional figure can also be called a plane figure since it can be drawn in the two dimensional plane. Some examples include the triangle, the square, the circle, the pentagon, the hexagon, the parallelogram, the rhombus, etc.

A hexagon is a 6-sided figure, while a pentagon is a 5-sided figure. A school crossing sign in the United States is a pentagon. In many cases, hexagons and pentagons have sides that are all the same length, although this is not required.

A polygon is a closed plane figure made up of several line segments that are joined together. The first 10 are: the triangle, the quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, decagon, hendecagon, and the dodecagon.
a 2d shape A two dimensional figure can also be called a plane figure since it can be drawn in the two dimensional plane. Some examples include the triangle, the square, the circle, the pentagon, the hexagon, the parallelogram, the rhombus, etc.
Polygon is a shape that is has straight lines and it is a close figure some polygon shapes are sqaure, rectangle, triangle, pentagon, octagon, hexagon and some other more
That would be a pentagon...
A figure with twice as many sides as a triangle would be a hexagon. Also known as a 6 sided figure.
