Lay out a ram's horn step by step

1.1 Follow the outline of the ram's horn on the left

1.2 Redo the plan and emphasize tangents. You should pay more attention to straight lines than curves. Let the central points appear without any connection between them, except for the sequence of successive tangent connections to the same point.

2.1 The thickest part on both sides of the figure

2.2 A is the midpoint

Determine the size of the basic part:

We use a triangle Define key points on the perimeter at which the vertices of the triangle will be. Split the sides of the triangle according to the points on the perimeter we want to fix. In equal parts, each side of the triangle and the line perpendicular to it are determined as an axis, and the coordinates of the points in the middle are used to determine the outline. Finally note the relationship between the triangles used.
