Question

How do i proove one quadrilateral is another quadrilateral also...pls give me th eproperties used in proving another quad.......for eg: proove tht a square is also a rectangle @Hesan

Answer 1

Oooh... proving...

Now, what are the properties that define a rectangle?

Answer 2

okay i dont want to solve the example.cuz i knw.pls help me by saying how to do it for all quadrilaterals

Answer 3

The example cannot be proved (simply because it's false, a rectangle need not be a square).

So perhaps you have another example? Your original question, perhaps?

Answer 4

no there are thousans of question like tht in tht lesson i just wanna knw all the basics.like a para ia also arhombus a rectangle and stuff like tht i would also like to knw all the properties of all quad plss help @terenzreignz

Answer 5

Parallelogram is also a rhombus? False!
LOL

The only general guideline I guess is to know ALL the definitions.

Answer 6

That's unless you can present a specific example... in which case, I can demonstrate :D

Answer 7

screw u mann i knw paralellogram is aspere ..it is also a square a rectangle etc

Answer 8

screw u is only a sarcasm

Answer 9

@terenzreignz cmon stop givin false info and gimme correct info

Answer 10

@Preetha

Answer 11

Pardon?
I don't give false information when mathematics is concerned...

Answer 12

just kidding SARCASM

Answer 13

nw say me hw i do it

Answer 14

Like I said, the only general guideline is to be acquainted with definitions.
I mean REALLY acquainted.

We can only go further if you present a SPECIFIC proving question that we can work on together, that way, I can thoroughly demonstrate a technique on proving. (Emphasis on *a* technique, and note that it is not *the* technique, as there are many ways to prove)

Answer 15

okay atleast give me properties of all quadrilaterals

Answer 16

Quadrilateral means one thing and one thing only: A polygon with exactly four sides.

Answer 17

okay i mean all shapes

Answer 18

Let me start again:

Answer 19

With the definition of a Quadrilateral on the table, let's define a few special ones.

Answer 20

A trapezoid is a quadrilateral with EXACTLY one pair of parallel sides.

Answer 21

A parallelogram is a quadrilateral with two pairs of parallel sides.

Answer 22

Now with the definition of a PARALLELOGRAM on the table, let's have a few special ones:

Answer 23

A rectangle is a parallelogram with all four internal angles congruent. (Consequently, all four said angles must be right angles.)

Answer 24

A rhombus is a parallelogram with all four sides congruent.

Answer 25

A square is a parallelogram with all four internal angles congruent, as well as all four sides.
Thus, a square falls under both rectangle and rhombus.
