Exercise of geometry by the group 5

Take a lead pencil and draw the figure described below :
Firstly draw an equilateral triangle ABC, the sides have a length of 10cm. Draw the height of AB, (HC). Then do all the bisectors of the triangle. Draw a circle, which has as center the intersection of the bisectors, called C, with a radius of 2cm. After, draw another circle, C', with C as center and for radius [HC]. C' cut (HC) in N. Now draw a new circle C'' with the same diameter that C. Finally you must erase the bisectors and C'. You have finish. Congratulate.

Question bonus : Now try to find what this figure represent. An indication, we are 37 hours in.

Good luck!=D

    We have followed the instructions undtil we were tould to cut the c’ out (HC) in N. What do you meen by that? And what is N?

  2. teruelr says

    N is the intersection point of (HC) and the circle C’ .

  3. teruelr says

    N is also the center of the circle C”.
    Sorry for the mistake. ; )
