Answer:

360 degrees

Step-by-step explanation:

A rotation symmetry angle is an angle with which a figure is rotated and still looks the same as if it wasn't turned.

For example, a square has a minimum angle of rotational symmetry of 90 degrees, because if you turn it by 90 degrees, it still looks exactly the same way.

This rotational symmetry is mostly used with regular shapes.

This quadrilateral is not a regular shape, and there's only one way to have it look exactly like it is now... and it's to do a full turn, of 360 degrees.

Are all negative numbers really 0

algol13

Answer:

Thus every real number other than zero is either positive or negative, while zero itself is not considered to have a sign. Positive numbers are sometimes written with a plus sign in front, e.g. +3 denotes a positive three.

AB contains points (2, 1) and (-1, -8). What is the equation of the line parallel to AB that contains point (0, 2)?

Iteru [2.4K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points that belong to the AB line:

$(x_ {1}, y_ {1}) :( 2,1)\\(x_ {2}, y_ {2}): (- 1, -8)$

We can find the slope:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-8-1} {- 1-2} = \frac {-9} {- 3} = 3$

By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to AB will have slope $m = 3$ , then the equation will be of the form:

$y = 3x + b$

We substitute the given point and find b:

$(x, y) :( 0,2)\\2 = 3 (0) + b\\2 = b$

Finally, the equation is:

$y = 3x + 2$

Answer:

$y = 3x + 2$
