You can use
GeoGebra to draw angles. There are two methods you can use: The first method is to specify three points or two lines that define the angle. The second method is to specify the desired size of the angle.
GeoGebra Instruction 1

Graphics Viewor clicking on the two lines from Step 2. Recall that angles are drawn counterclockwise.
Algebra View. Notice that the sides of the angle have the same length. If you want to see the sides from the vertex to the endpoints, use the
Segmenttool to draw the segments between the points so that they will be visible. Feel free to experiment drawing angles with different sizes.

If you want your angle to go clockwise, select the box below the text field.

Here, you choose the
Angle with Given Size tool because it can precisely draw the angles you desire. You therefore follow Item 8 and type in the size of each angle.
