This shape appears to be quite simple, like a triangle with the top corner cut off. However, its dimensional constraints are a bit complex. Let’s see how we can use drawing techniques to achieve it.

Steps:

- Draw a straight line with a length of 41 and an angle of 32
- Draw an auxiliary circle with a radius of 29 at the endpoint below
- Draw a perpendicular line of any length at the endpoint above
- Use the copy command to copy and horizontally move a straight line distance of 80
- After taking the intersection point of a circle and a straight line, draw a straight line to connect the corresponding nodes
- Delete auxiliary lines
- Use the Modify>Corner command to connect straight lines
- Mark and verify the results
