How to draw an oval?
There are many ways to draw an oval. The article presents the two simplest options: how to draw an oval with a compass, pencil and ruler, without using patterns.
Drawing an oval with a diamond
- Before building the oval, it is necessary to draw an equilateral, horizontal rhombus with a larger diagonal.
- From the upper top of the rhombus, draw two segments that will divide in half the lower sides of the rhombus. From the other vertex of the rhombus, which is visually located below, also draw two similar segments. The result is four triangles: left and right.
- At the intersection of each pair of triangles, a point should be designated - it is in this area that the leg of the compass should be placed and the arc side walls of the oval should be drawn.
- Of the vertices used for the segments, draw the missing sides of the oval below and above with compasses.

If the major axis is known
If the size of the major axis of the oval is known, then the construction itself is many times simpler.
The specified axis should be divided into three equal parts, as in the photo:
Measure distance O1 and O2 is the radius. From these points draw circles of radius O1O2, as in the photo:
The intersection of the circles is called m and n.
The points m and n with O1 and O2 are connected, resulting in a straight line, which must be extended to the intersection with the circles. Points 1, 2, 3, 4 in this case are points of conjugation of arcs.
The points m, n are assumed to be centers and from each radius we draw the maximum radius, which is equal to n2 and m3. Arcs 12 and 34 are obtained.
