Question

Two quadrilaterals EFGH and IJKL are drawn on a coordinate grid. The coordinates of the vertices of each quadrilateral are given below.

EFGH – E (1, 4), F (2, 4), G (2, 2), H (1, 2)
IJKL – I (-4, -1), J (-1, -1), K(-1, -7), L(-4, -7)

Which statement about the two quadrilaterals is true?


The side lengths of IJKL are half of the corresponding side lengths of EFGH.
The side lengths of IJKL are three times the corresponding side lengths of EFGH.
The side lengths of IJKL are congruent to the corresponding side lengths of EFGH.
The side lengths of IJKL are not proportional

Answer 2

I would plot the points, just to see what is what.
Then I would use the distance formula to find the lengths of each side.

for two points (x1,y1) and (x2,y2)
distance = sqrt( (x1 - x2)^2 + (y1- y2)^2)

Answer 3

I already found this out thanks. I need help on my last question though.
