What is bilatteral symmetry?

It is reflectional symmetry, but only one line of reflectional symmetry

How do you find the number of degrees needed to need to rotate an object so the image matches the original?

You divide the number of equal sides/figures of the shape, and divide 360 by that number.

What are all the letters of the alphabet that have rotational symmetry?

H, I, S, X, and O.

What formula do you use to solve a problem such as this example:

How many two person conversations are possible at a party of 42?

You use the formula

for this specific problem!

n(n-1)

2

The N value is the x value (number of people total) and 2 symbolizes the y value which is the two person conversation

How would you go about trying to find a counter example to prove a conjecture wrong, such as for the following problem?

If a number can be divided by 4, it can be divided by 8

Look at the multiples of each.

Start immediatly with the opposite of what it's asking you!

Rhombus, Square, Rectangle, Parralelogram, and Quadrilateral

In a triangle, if given the centroid and the whole length of a segment going through the centriod, what is the length of ech segment if one of them is longer then the other.

The longer length segment is 2x and the shorter length is x

How do you find the slope of two given points?

 y₂- y₁

x₂- x₁

How do you know if lines are perpindicular?

If the slopes of each line/equation are opposite recipricals

What steps do you take to find the perpindicular line of a given equation when you are also given a set of points along with an equation in slope-intercept form to make it perpindicular?

First, you wan to find the slope of the given equation.

Second, you plug in that slope into a slope-intercept form equation with the given set of points and plug it in to find the b value.

Next, simplify that equation and you are done!

What is the sum of all exterior angles of a figure?

360 degrees

When looking for degree measurements of arcs, what should you do first?

Find all of the interior angles and use those as the exterior angles

OR

1/2 diagnol 1 + diagnol 2

How do you find the area of an annulus?

∏R^{2 -} ∏r²

OR

^{Big circle's area - small circle's area}

How do you find the area of a regular polygon?
