The angle ruler consists of two scales with a measuring range of 15CM and an angle scale. We design the minimum scale of the ruler scale as an increasing point, changing the length of the traditional scale to be the same, so that people can clearly know the number of millimeters. The steps of drawing an angle with an angle ruler are as follows: 1. Draw a ray with the positioning line of the zero scale line as the end point. 2. Select the angle you need in the angle scale and mark it. 3. Connect the end points and marks of the rays to form an angle.

Hello, do you need cooperation! My side is to do the hand board
This scheme has invalid patents
Fucking good
Awesome, real design. However, there is a small bug. The angle of 150 is called obtuse angle, not acute angle.
Can the middle be made hollow? The line feels too long.
This is really amazing. Some of them are amazing.
Good creative
