Open-book stick figure

Using simple geometric math skills, you can also draw book patterns. Use a tool ruler to walk straight lines and line segments with dimensions, and use a protractor to walk arcs and straight lines with dimensions. Let's see if the scale is the same (using line segments and arcs correctly). First, connect the straight line and arc with scales and inches, and then see the pattern effect after connection. This is followed by geometric drawings of various books.

Unexposed secrets

Steps: Draw all the parallel book edges on the paper with a ruler, and then draw the pages into a pop-up book shape with a protractor. Pay attention to wipe off many strokes with an eraser when drawing. After painting, see if it is inappropriate and make some changes. So I drew a flat book or notebook.

A person (or thing) that is easy to understand

Steps: It is also easier to spread out large paper and draw open books. Please fold the 16 paper in half and unfold it. Use a protractor to draw the upper and lower four equal plane radians on the left or right side of the middle of the redrawing paper. Please ask the ruler and pencil to draw the bisecting line between the two sides and the middle of the open book again. See what's wrong and fix it with an eraser and pencil, so that the opened book can be drawn successfully.

Multiple books

Steps: first draw all the edges of the book on the paper with a ruler, and then draw the pages into a pop-up book with a protractor. Pay attention to using an eraser when drawing. After painting, see if it is inappropriate and you can modify it.

Last time I revised my opinion, I asked to write down the steps. One step at a time is too much, isn't it?
