How to draw a 60 degree angle with a geometry artboard

A lot of students in the study of geometry will use a number of auxiliary tools, geometric artboard is one of them . It is often used to draw various geometric shapes, even some dynamic ones, such as triangles, circles, polygons, and so on. Using the geometry artboard to draw some basic graphics is actually very simple, if not, you can also learn about the tutorials. Here's a tutorial to share how to draw a 60 degree angle with a geometric artboard?

The specific drawing steps are as follows:

Step one constructs the ray. Select the left toolbar "Ray Tool", click on the artboard anywhere on the mouse, determine the endpoint a ray, and then drag the mouse, the ray came out, here hold the "Shift" key, click the mouse in the appropriate location, construct a horizontal ray AB.

To construct a ray AB example in a geometry artboard

Step two constructs an edge AC at a 60 degree angle. Double-click Point A to mark the center of rotation, select point B and Ray AB, select "Transform"--"rotate", enter angle 60 in the box, as shown, and then click "OK" to get the other side of the corner.

The other side of the angle is constructed using the rotation angle example

Step three marks the corner. Using the Geometry artboard marker tool, place the cursor at point A, and drag to mark the corner by pressing the mouse over the inside corner. Measured, ∠bac=60°, is exactly the desired angle.

Example of marking angles and measuring angles

The above is how to use the geometry of the drawing board to draw 60 degrees angle of introduction, is not it felt to draw a known degree of angle is not difficult? In fact, the geometry of the artboard contains a lot of powerful features, you can do a lot of things on the blackboard to work on a half-day to draw graphics, such as drawing a known triangular length of the triangle, using a geometric artboard can be easily drawn. If you do not want to make graphics, you can also download the geometry of the artboard courseware to use.
