Now we are getting more advanced! You will now construct a given angle at some other place. To do this, you use congruent triangles. It is a fact that two triangles with equal sides have equal angles. |
You see that angle at the point B? Create the same angle at B* The trick is already visible in the construction. You need to construct congruent triangles ABC and A*B*C*. All sides must have the same lengths! The solution is here. |
