Geometric figures can be drawn using a compass and a straight edge. This is commonly known as ruler and compass construction.
circle
I am not aware of any "geometric figure 8" - before finding the area of such a figure, you have to determine clearly how exactly it is defined. For example, you can draw two exact circles, or two ellipses - but that's not always exactly how it is drawn.

An 11-sided figure, known as a hendecagon or undecagon, is a polygon with 11 straight edges and 11 vertices. If regular, all sides and angles are equal, creating a symmetrical shape. Its appearance resembles that of a star or a complex geometric figure, depending on how it is drawn, but fundamentally, it maintains a distinct 11-sided outline.

circle
Circle in 2D is a straight figure drawn on a plane. But if we take it as a sphere,it cannot be straight.
that it could be drawn using just a compass and straight edge
If the compass angle is changed, the entire geometric shape being drawn is different. For example, if a triangle is being drawn, it could change from an obtuse triangle from a ninety degree triangle.

A compass.
A ten-sided geometric figure could have ten triangles drawn inside it, if you connect the vertexes. 8 triangles
An isosceles triangle has 3 sides and 2 of its sides are of equal length which can be constructed by using a straight edge and a compass.
