Question

Prove: In an equilateral triangle the three medians are equal.

Answer 1

do you know the distance formula?

Answer 2

you can use that to solve for the lengths of AQ, RB, and CP.
They should have the same results.

Answer 3

d=sqrt(x2-x1)^2+(y2-y1)^2

Answer 4

yes.

so now, let's find the distance of AQ using that formula. What will you get?

Answer 5

\(\sf x_1= 0, y_1 = 0\\ x_2 = \dfrac{3a}{2}, y_2=\dfrac{b}{2} \)

Answer 6
