Drawing Latitude and Longitude lines on a sphere is an amazing way to doodle your way to three-dimensional confidence. Famousandfaded ^(https://www.blogquicker.com/goto/https://sketchfab.com/famousandfaded) created this wonderful tool to help you see the lines and use them as a reference. This is an interactive model. You can enlarge it to fill the full screen. Then use your mouse to rotate the globe. Notice how the latitude and longitude change their shapes as you do so. Remember these are straight lines. But as they wrap around the sphere, we see these distortions.
How to use the Model
Enlarge the model to full screen. Grab a piece of paper, draw a circle, and then draw the latitude and longitude lines from the model. Rotate the model and repeat. Make some quick sketches and other careful drawings, trying to reproduce the angles you see as exactly as possible. Do not worry about making a pretty picture. The thing that will help you the most is a lot of repetitions. You will come away with a new understanding of how straight lines wrap around a sphere.
