Explain how you can differentiate between a square, rhombus, and rectangle based on the angles formed by their diagonals.
Answer:
Quadrilateral just means "four sides"
(quad means four, lateral means side).
A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Step-by-step explanation:
propertiesA quadrilateral has:
four sides (edges)
four vertices (corners)
interior angles that add to 360 degrees:
Quadrilateral Angles
Try drawing a quadrilateral, and measure the angles. They should add to 360°
Types of Quadrilaterals
There are special types of quadrilateral:
Types of Quadrilateral
Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See below for more details.
Let us look at each type in turn:
The Rectangle
Rectangle
the little squares in each corner mean "right angle"
A rectangle is a four-sided shape where every angle is a right angle (90°).
Also opposite sides are parallel and of equal length.
The Square
Square
the little squares in each corner mean "right angle"
A square has equal sides (marked "s") and every angle is a right angle (90°)
Also opposite sides are parallel.
A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
The Rhombus
Rhombus
A rhombus is a four-sided shape where all sides have equal length (marked "s").
Also opposite sides are parallel and opposite angles are equal.
Rhombus Diagonals
Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
A rhombus is sometimes called a rhomb or a diamond.
The Parallelogram
Parallelogram
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same).
NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Example:
Square
A parallelogram with:
all sides equal and
angles "A" and "B" as right angles
is a square!
The Trapezoid (UK: Trapezium)
Trapezoid (or Trapezium) Trapezoid (or Trapezium)
Trapezoid
Isosceles Trapezoid
A trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.
And a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides:
Trapezoid Trapezium
In the US: a pair of parallel sides NO parallel sides
In the UK: NO parallel sides a pair of parallel sides
(the US and UK definitions are swapped over!)
An Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.
The Kite
The Kite
Hey, it looks like a kite (usually).
It has two pairs of sides:
Each pair is made of two equal-length sides that join up.
Also:
the angles where the two pairs meet are equal.
the diagonals, shown as dashed lines above, meet at a right angle.
one of the diagonals bisects (cuts equally in half) the other.
... and that's it for the special quadrilaterals.
Irregular Quadrilaterals
The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.
The "Family Tree" Chart
Quadrilateral definitions are inclusive.
Example: a square is also a rectangle.
So we include a square in the definition of a rectangle.
(We don't say "Having all 90° angles makes it a rectangle except when all sides are equal then it is a square.")
This may seem odd, as in daily life we think of a square as not being a rectangle ... but in mathematics it is.
Using the chart below we can answer such questions as:
Is a Square a type of Rectangle? (Yes)
Is a Rectangle a type of Kite? (No)
Quadrilateral Classification
Complex Quadrilaterals
Oh Yes! when two sides cross over, we call it a "Complex" or "Self-Intersecting" quadrilateral, like these:
Complex Quadrilaterals
They still have 4 sides, but two sides cross over.
Polygon
A quadrilateral is a polygon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on.
Play with Them
Now that you know the different types, you can play with the Interactive Quadrilaterals.
Other Names
A quadrilateral can sometimes be called:
a Quadrangle ("four angles"), so it sounds like "triangle"
a Tetragon ("four polygon"), so it sounds like "pentagon", "hexagon", etc.

The sum of 6 times a number and 7 is 8.
Use the variable x for the unknown number.
Answer:
6x + 7 = 8
Step-by-step explanation:
Let x represent the unknown number.
Translating the word problem into an algebraic expression, we have;
6x + 7 = 8
To find the value of x;
6x = 8 - 7
6x = 1
x = 1/6

One side of a rectangle is three times as long as another. If its area is 363 square centimeters, find its dimensions.
Shorter side:
Longer side:
9514 1404 393
Answer:
11 cm by 33 cm
Step-by-step explanation:
You can solve this problem mentally as follows.
Consider the rectangle as 3 squares, side-by-side. Then the area of each of those squares is 363/3 = 121 cm^2. From your knowledge of the squares of numbers, you know that 121 = 11^2. So, the width of the rectangle is 11 cm, and the length is 3 times that, or 33 cm.
_____
Using variables, we can let w represent the width. Then 3w can represent the length, and the area is ...
A = LW
A = (3w)(w) = 3x^2 = 363
w^2 = 363/3 = 121
w = √121 = 11
3w = 3·11 = 33
The width is 11 cm; the length is 33 cm.
Answer:
Shorter side: 11 cm
Longer side: 33 cm
First, write down what you know:
length=3*width, this can be written as 3w
area=363 sq cm
Now we know the formula for the area of a rectangle= length * width so we can substitute what we know into the formula. It looks like this:
363 (area) = 3w (length) × w (width)
[tex]363=w^2[/tex]
divide both sides by 3 to get: 121 = [tex]w^2[/tex]
take the square root of both sides to get: w=11 (square root of 121 is 11)
Now that we know what the width is, we can substitute that and find the length: 3w = 3 × 11=33
So length (longer side) is 33cm and width (shorter side) is 11cm.
*To check this, plug the numbers into the area formula: Area=33 × 11 = 363 sq cm.

Can i get brainliest?
Hi there!
[tex]\large\boxed{x = 18}[/tex]
3x + 2x + 90 = 180
Begin by combining like terms:
5x + 90 = 180
Subtract 90 from both sides to isolate for x:
5x + 90 - 90 = 180 - 90
5x = 90
Divide both sides by 5 to further isolate:
5x/5 = 90/5
x = 18.

Please help I keep getting them wrong.
Answer:
(2, 2)
Step-by-step explanation:
Since we know that y = x, we can substitute that into the first equation and solve for y.
-(y) + 3y = 4
2y = 4
y = 2
And once more, since we know that y = x, we now know that x is also 2.
Therefore, the solution is (2, 2).
