Question

help please.

Answer 1

Questions here.

Answer 2

@Directrix

Answer 3

Read the coordinates of points A, B, C, and D from the graph and post them here.

We will need those to get the slopes of the segments.

Answer 4

A is 2,1/2 B is 2,4 C is 61/2 D is 6,4 is this right? @Directrix

Answer 5

@Directrix

Answer 6

Where does the comma go for these coordinates: C is 61/2

Answer 7

I think that the coordinates are messed up. See attached.

Answer 8

Oh ok.

Answer 9

>>A is 2,1/2 B is 2,4 C is 61/2 D is 6,4 is this right?

No, start over.

Start at the origin. Point A is 1 over and 3 up so A is (1, 3).

Answer 10

Oh ok i understand.

Answer 11

B is 4,3
C is 7,7
D is 3,7

Answer 12

Check D again.

Answer 13

Oh 4,7 lol

Answer 14

A is (1, 3)
B is (4,3)
C is (7,7)
D is (4,7 )


What is the slope of segment AB? A is (1, 3) ; B is (4,3)

Answer 15

Slope(m)=
0

Answer 16

ok

Answer 17

Yeah.

Answer 18

What is the slope of segment CD? C(7,7) ; D(4,7)

Answer 19

Slope(m)=0

Answer 20

If two lines have the same slope, then they are parallel.

Segment AB is parallel to segment CD because both segments have a slope of 0.

Answer 21

Next step is to show segment BC parallel to segment DA.

Answer 22

ok

Answer 23

What is the slope of segment BC ? (You can look up the coordinates this time.)

Answer 24

Slope(m)=1.333

Answer 25

That is 4/3 in disguise.

Answer 26

What is the slope of segment DA?

Answer 27

Slope(m)=
1.333

Answer 28

Segment BC is parallel to segment DA because both segments have a slope of 4/3.

Answer 29

Oh ok

Answer 30

A is (1, 3)
B is (4,3)
C is (7,7)
D is (4,7 )
---------

Theorem:

If two lines have the same slope, then they are parallel.

Therefore,

Segment AB is parallel to segment CD because both segments have a slope of 0.

Segment BC is parallel to segment DA because both segments have a slope of 4/3.
---------
Quadrilateral ABCD is a parallelogram because it has both pairs of opposite sides parallel. By definition, ABCD is a parallelogram.

Answer 31

Is that what i put as the answer?
