In this assignment, you have to construct a similar triangle. Two triangles are similar, if they have the same angle.

 

Construct a triangle A*B*C*, similar to ABC.

  • First we measure the angles. Select the angle tool. Click on BAC and ABC.
  • To see the sizes, right click on the angles, and enable the size display (reading 0.2 in the icon).
  • Now we copy the angles. Select the fixed angle tool. Click on B*, A* and then somewhere close to C*.
  • Leave the dialog with "Set size" and click on the angle at A.
  • Copy the angle at B to B* the same way.
  • Create the intersection C*.

This finishes our tutorial about angles!
