Properties of parallelograms

can be observed through

symmetry.

Definition: A parallelogram is a quadrilateral with

two sets of opposite sides parallel.

Definitions need no further observations, as they are stated facts.

A parallelogram has rotational symmetry when rotated 180º about its center.

A parallelogram has no reflectional symmetry.

Answer:

A parallelogram has two pairs of parallel sides.

(of figures) identical in form; coinciding exactly when superimposed.

Symmetry is a characteristic feature of geometric shapes, systems, equations, and other material objects, or abstract entities, related to their invariance under certain transformations, movements, or exchanges. There are five clearly established types of symmetry: Rotation.

Solve the system of equations using substitution or elimination. Show all work for credit.

Tomtit [17]

Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
$y = \frac{ - \frac{1}{2} x + 2}{3} \\ y = - x + 9$

Since both expressions are equal to y, you have to equal both expressions like this:
$\frac{ - \frac{ 1}{2}x + 2 }{3} = - x + 9$
Now you can solve the equation:
$- \frac{1}{2} x + 2 = 3( - x + 9) \\ - \frac{ 1}{2}x + 2 = - 3x + 27 \\ \\ - \frac{1}{2} x + 3x = 27 - 2 \\ \frac{5}{2} x = 25 \\ x = \frac{(25)(2)}{5} \\ x = 10$
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result

$y = - (10) + 9 \\ y = - 1$
So, the answer is x=10 and y=-1

The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. find the measure o

saul85 [17]

2 angle A and B are Complementary means that the sum of their measures is 90°.

2 angle A and B are Supplementary means that the sum of their measures is 180°.

Thus, if the measure of angle A is x:

the measure of the supplement is 180°-x
the measure of the complement is 90°-x

"The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. "

let the measure of the angle be x, then we have:

180°-x=40°+2(90°-x)

180°-x=40°+180°-2x

2x-x=40°

x=40°

Answer: 40°
