Question 161972: If ef is 2a and f is the midpoint of line eg, how long is the eg?: If ef is 2a and f is the midpoint of line eg, how long is the eg?

You can put this solution on YOUR website!
If f is the midpoint of eg, then the length ef must be equal to the length fg.
ef = fg = 2a
So eg = ef + fg
eg = 2a + 2a
eg = 4a
