Isosceles right triangle ABC is shown. 3
A
3
In a right triangle DEF,4D is the right angle, the length of DE is 2 times the length of AB, and the length of DF is 4 times the length of AC.
How many times greater is the length of EF than the length of BC?

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
