Answer 4

Do you mind sharing yours?

Answer 5

nice!

Answer 6

no problem..
triangles A0A1C1, A1B0B1, B1C0C1 are congruent..
so, accordingly angle B1A1B0+angle A1B1B0=120
angle B1A1B0=angle C1B1C0
so, angle C1B1C0+ angle A1B1B0=120
so, angle A1B1C1=180-120=60
hence u can prove all the angles of the smaller triangle to be equal to 60, ie: equilateral

Answer 7

Hmm, once they are congruent, i think we can applyy ' corr. sides, congruent triangles' to prove it is an equi. triangle. Thank you so much!!!!!

Answer 8

yep.. i am fool
