| Indeed, the sum is a polygon whose vertices are obtained as the sums of vertices of the addends. |
| If all the vertices of a hexagon lie on a conic, and if the opposite sides intersect, then the points of intersection lie on a line. |
| The particular tablet which interests us here investigates how to calculate the radius of a circle through the vertices of an isosceles triangle. |
| Similarly, the vertexes of an hypocycloid are the points on the curve that coincides with an inscribed circle. |
| A dodecahedron or is a geometric form with 12 pentagonal surfaces, 20 vertexes and 30 ribs. |
| The tensions of the vertexes of the base are compensated by the tension of the upper point. |
