Question

Can anyone help me on this geometry question and explain it?​

Answer 1

The length of FG is 5.

Explanation:

We can use the distance formula to solve.

D =
`\sqrt{ (x2 - x1)^(2) + (y2 - y1)^(2) }`

D =
`\sqrt{ (1 - -2)^(2) + (0 - -4)^(2) }`

D =
`\sqrt{ 3^(2) + 4^(2) }`

D =
`√( 9 + 16 )`

D =
`√(25)`

D = 5
