Polygon ABCD is a quadrilateral. What would prove that ABCD is a parallelogram

Mathematics
1 answer:
masya89 [10]3 years ago
6 0

Answer:

Step-by-step explanation:

Parallelogram are square, rectangle, rhombus, and rhomboid and all with opposite lines that are parallel. Where each angle add up to 360. There are many quadrilaterals that are not parallelogram lesser known ones like convex quadrilaterals that are not parallelograms as they have no parallel lines and do not add up to 360. Polygons that intersect are not parallelograms. We can therefore show upon the parallelogram that there are 2 parallel lines within 4 lines of ABCD and if needed used in analogy with a 3 vertices triangle. Parallelogram like other quadrilaterals have 4 vertices but the angles of a parallelogram would alternate when drawn corner to corner. Diagonals must intersect at the opposite angle. We call them diagonals (not diagonal line) on a parallelogram, simply as where one crosses the other crosses and they become the plural.

Twice the difference of a number and six is the same as twelve . Write into algebraic equation
DiKsa [7]

Answer:

2(n-6)=12

(I went too far in my explanation; I'm not going to erase it because I think it is important to have an example on solving these)

Step-by-step explanation:

Twice the difference of a number and 6 is the same as 12.

Twice means 2 times

Difference means the result of subtracting something.

is the same as means equal to (=).

So we are given 2(n-6)=12.

You can start by dividing 2 on both sides are distributing 2 to terms in the ( ).

I will do it both ways and you can pick your favorite.

2(n-6)=12

Divide both sides by 2.

 n-6  =6

Add 6 on both sides

 n     =12

OR!

2(n-6)=12

Distribute 2 to both terms in the ( )

2n-12=12

Add 12 on both sides

2n    =24

Divide both sides by 2

n       =12

Nataly_w [17]

Answer

36/9= 4

Step-by-step explanation:

This is a fraction equal to

36 gallons ÷ 9 minutes

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 9

36 gallons ÷ 9

9 minutes ÷ 9

=

4 gallons

1 minute

=

4 gallons

minute

= 4 gallons per minute
