This triangle is inscribed with a flower-shaped figure. How can we make 5 tangent circles that are exactly inscribed within the triangle? We know that the Align command can scale and move similar figures. Let’s try using the Align command.

Steps:

- Draw a straight line with a length of 60
- Draw circles with radii of 40 and 50 at both ends of the line
- Connect the intersection points of circles into triangles
- Draw a regular Pentagon at random, then draw multiple circles with the vertex as the center and the side length as the diameter
- Use the parallel line command to draw parallel lines on the edges of a triangle, so that the outer triangle is similar to the destination triangle (use “corner” command to connect non intersecting lines)
- Use “align” command to scale and align the internal shape to the destination triangle
- Add hatch and annotations after trimming
