Bisecting diagonals
Two pair of opposite parallel sides
Two pair of opposite equal angles
Solution:
Let us first define the properties of parallelogram.
- The opposite sides of a parallelogram are parallel.
- The opposite sides of a parallelogram are equal.
- The opposite angles of a parallelogram are equal.
- The diagonals of a parallelogram bisect each other.
Now, let us define the properties of square.
- All four sides of a square are equal.
- Opposite sides of a square are parallel.
- Opposite sides of a square are equal.
- Opposite angles of a square are equal.
- Diagonals bisect each other at 90°.
From these properties, we can conclude that every square can always be classified as a parallelogram if
- Bisecting diagonals
- Two pair of opposite parallel sides
- Two pair of opposite equal angles

8x8= 64
Answer:
-3x +8
Step-by-step explanation:
Apparently, you want to simplify the expression. That means you want to "collect terms", or "combine like terms."
"Like terms" are ones with the same variable structure. Here, the three terms in the expression are (-2x), (-x), and (+8). The ones that both have x as a variable are (-2x) and (-x). The way we combine these is to add the coefficients of the variable:
(-2x) +(-x) = x(-2) +x(-1)
= x(-2 -1)
= x(-3)
= -3x
So, the two "x" terms combine to give -3x. The constant term (+8) is not combined with anything. The simplified expression is then ...
-3x +8

<em>Additional comments about writing and combining terms</em>
When math symbols are written next to each other, it means they are multiplied. -2x means (-2) × (x). It can be written several ways, including ...
- -2x
- (-2)x
- x(-2)
- (x)(-2)
- (-1)(2x)
Usually, the coefficient is written in front of the variable. In the above, we have chosen to write the coefficient after the variable so that the expression shows some parallelism with the usual expression of the <em>distributive property</em>:
a(b +c) = ab +ac
x(-2 -1) = x(-2) +x(-1)

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>
given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.
we already know that 1m = 100cm.
so, each side of this cube is 100cm in length.
so,
To find what is the volume in cubic metres.
so, the rate is

Option B: a counterclockwise rotation of 90° about the origin
Explanation:
From the graph, we can see the coordinates of the figure A are (0,2), (-1,6) and (-4,4)
The coordinates of the figure A' are (-2,0), (-6,-1) and (-4,-4)
<u>Option B: a counterclockwise rotation of 90° about the origin
</u>
The transformation rule for a coordinate to reflect a counterclockwise rotation of 90° about the origin is given by
Let us substitute the coordinates of the figure A
Thus, we have,
Thus, the resulting coordinates are equivalent to the coordinates of the figure A'.
Therefore, the figure is a counterclockwise rotation of 90° about the origin
.
Hence, Option B is the correct answer.
