Question

Find the midpoint of diagonal BD.

Figure ABCD is shown. A is at negative 3, 2. B is at 0, 6. C is at 6, 6. D is at 3, 2.

(1, 3.5)
(1.5, 4)
(2, 3.5)
(2, 4)

Answer 1

You know the x- and y- coordinates of B and D. Please look up the "midpoint formula" and apply it to this situation, substituting these coordinates into the formula as appropriate. (Google "midpoint formula.")

Answer 2

I know the midpoint formula but im not sure what goes where

Answer 3

M= (x1+x2, y1+y2)
2 2

Answer 4

B is the point (0,6) - x is 0 and y is 6
D is the point (3,2)

do you get that?

Answer 5

Okay give me a minute to work it out

Answer 6

wait no, im still confused, can you give me what the coordinates are for x1,x2 and y1 and y2 Please I will work it out

Answer 7

(x1,y1) = ( 0,6)

Answer 8

(x2,y2) = (3,2)

Answer 9

Okay so M=(0+3, 6+2)
2 2

3/2 + 4
= 4 3/2

Answer 10

I mean (3/2, 4)

Answer 11

do you know what the midpoint formula is?

Answer 12

I have already worked it out above. could you check

Answer 13

your answer was almost right it is suppose to be (-3/2, 2)

Answer 14

could you explain how you got this

Answer 15

so x1 = 0, x2 = 3, y1 = 6, y2 = 2 then you just plug these values into the formula

Answer 16

I did this and got M=(0+3, 6+2)
2 2

Answer 17

oh lol yeah you are right I was looking at the wrong thing sorry

Answer 18

Ok thank you could you check another problem

Answer 19

sure tag me when you are done I will be right back

Answer 20

Thanks and its just like nameing the shape
Quadrilateral ABCD has coordinates A (3, 5), B (5, 2), C (8, 4), D (6, 7). Quadrilateral ABCD is a

rectangle, because opposite sides are congruent and adjacent sides are perpendicular
square, because all four sides are congruent and adjacent sides are perpendicular
parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular
rhombus, because all four sides are congruent and adjacent sides are not perpendicular

Answer 21

Your graph is much better than mine, so look up the things I do in my graph on your graph because you'll get a more accurate look.

Answer 22

The first thing we need to do is to see if any sides are congruent.
