What additional information do you need to prove NOP=QSR?
Lorico [155]
After careful consideration i think I have an answer... 
So if you notice, These two triangles are a reflection of each other. 
Now even though these two triangles equal one another, we still have to consider the fact that they are different. (one side is the opposite of another)
So lets just name all the sides that equal each other. 
∠N = ∠Q
NO = QS
QR = NP
PO = SR
∠S = ∠O 
∠P = ∠R 

(by the way i'm going to be saying {the reflective side} every time i want to refer to the side with the two lines :P) - so bare with me. 

So therefore this would mean that ∠P = ∠S would be false, since one angle is from the side that is reflected and the other isn't. Makes sense?

So lets look over at the answers...

A.) PN = SQ 
For this answer choice, PN is on the non reflective side, while SQ is on the reflective side. Soooo... This answer choice is wrong. 

B.) NO = QR
NO  is part of the  unreflective side, while QR is part of the reflective side. 
Therefore this answer is wrong. They must be part of the same side. 

C.) ∠P = ∠S 
∠P is on the unreflective side, while angle ∠S is on the reflective side. 
There fore this answer is also wrong. 

D.) ∠O = ∠S 
Now ∠O is on the reflective side while ∠S is on the reflective as well. 
There fore this answer is correct . 

YOUR ANSWER IS. 
D.) ∠O = ∠S

Are all parallelograms quadrilaterals
spayn [35]

Yes! Every parallelogram is a quadrilateral.

<u>Explanation</u>

Every parallelogram is a quadrilateral. But vice versa is not true ie every quadrilateral is not a parallelogram.  Quadrilateral is a 4 sided polygon & parallelogram is also a 4 sided polygon but with some extra characteristics. That is the reason , every parallelogram is a quadrilateral. But if quadrilateral gets all those extra characteristics , then only it becomes a parallelogram.

the ratio of Ali's age to Ben's age is 21:17.If the difference in ages between them is 3 years and 4 months,find Ali's age,in ye
torisob [31]

Answer:

To find the answer from the question above, we need to solve the equation and find Ali's age. We know that the ratio of Ali's age and Ben's age is 21:17 and they have age's difference in 3 years and 4 months. We need to find how many years old is Ali in years and months.

First, we made an equation with the ration which has known

21/(21 +17) = 21/38x = Ali's age

17/(21+17) = 17/38x = Ben's age

Ali's age - Ben's age = 3 years 4 month

           21/38 - 17/38 = 4/38x = 3 years 4 month

and we use x as a symbol for the total of Ali's age and Ben's age

to make it easier, we change the unit of the time. from year to month

3 years + 4 months = (3 x 12 months) + 4 months = 40 months

we need to know what is the value of x, we can finish a first equation which is the age's difference

4/38x = 40 months

          x = 40/4 x 38

          x = 10 x 38 = 380 months

because we know the value of x is 380, now we can finish the other equation

Ali's age

          21/38x = 21/38 x 380 = 21 x 10 = 210 months

          * if we would know how many years old Ali in years and months then we change the unit, 1 year = 12 months so, 210 divided by 12 is 17 and 6 left. So Ali's age is 17 years and 6 months.

Ben's age

          17/38x = 17/38 x 380 = 17 x 10 = 170 months

         * we change the unit to year, so if 170 divided by 12 is 14 and 2 left.       So, Ben's age is 14 years and 2 months
