Question

Write a proof to show that a rectangle has congruent diagonals. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.

Please someone help, I do not understand.

Answer 2

the second question is

A kite is a quadrilateral with two pairs of adjacent, congruent sides. Prove the two angles between the non-congruent sides are congruent. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.

Answer 4

Hello

Answer 5

Hi can you help me?

Answer 6

Let's try

Answer 7

The bqd news is I'm on my tablet

Answer 8

Thats fine, I just need to get these two questions done soon

Answer 9

Ok

Answer 10

ohh.

Answer 11

@Christos

Answer 12

For us to prove this we trisnle congruency

Answer 13

Triangle

Answer 14

Let's pretend we have a rectangle ABCD WITH diagonals AC AND DB

Answer 15

Sorry I am back

Answer 16

I can't draw so picture the rectangle in ur mi

Answer 17

Mind

Answer 18

I really dont understand this, I just really need your help on what a good answer would be. I have been sat in front of my computer all day, and these are my last two questions. Please :(

Answer 19

OK

Answer 20

Thank you :)

Answer 21

So do you have any answers for the two questions?

Answer 22

We look at triangles ABC and DAC

Answer 23

No I'm truing to help you Im some kind of machine to come up with answers

Answer 24

Just follow my work understand how the answer can be obtained

Answer 25

Ok.

Answer 26

Our goal here is to prove that diagonal BC and Diagonal DA are congruent meaning they of the same length

Answer 27

Alright

Answer 28

OK radar has the drawing tool just let him do this,

Answer 29

I need to get these answers quickly I barely have any time left to turn this in :(

Answer 30

Oh yeah I can scratch this and give you e answer but what is the point in that

Answer 31

Just try to learn

Answer 32

I really have no time, I will just leave the questions blank. I am sorry.

Answer 33

Suit your self
E proof is really easy to grasp

Answer 34

All you need is SAS postulate

Answer 35

Yeah but I only have 5 minutes to turn this in. If You could just give me direct answers for the two questions, I could easily learn after I submit.

Answer 36

There is only one question? Prove diagonals of rectangles are congruent

Answer 37

Yes, also I asked
A kite is a quadrilateral with two pairs of adjacent, congruent sides. Prove the two angles between the non-congruent sides are congruent. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.

Answer 38

Anyways here goes how
In rectangle ABCD we know ac is congruent to bd
Ab is congruent to CD

Answer 39

Ok.

Answer 40

Is that all?

Answer 41

We also know ABCD have 90 angles
Therefore angle ACD is congruent angle Abd
Now we have established side angle side
Then triangle ACD is congruent to tirangle ABD

Answer 42

If two triangles are congruen, then the corresponding sides are congruent
It follows that BC is congruent to AD

Answer 43

Hence wve proven that two diagonals of rectangles are always congruent

Answer 44

I'm using the drawing provided by @radar
Thanks to him

Answer 45

The ends the proof
