I put this flowchart together years ago to help our students become familiar and identify quadrilaterals and their properties using side lengths and the slopes of the sides.  The information is usually gathered from a gridded Cartesian graph or sets of ordered pair vertices of the quadrilateral.

#### Information Needed or to be Derived:

Points:
$(x_1, y_1) \text{ and } (x_2, y_2)$

Pythagorean Theorem:
$\displaystyle c^2 = a^2 + b^2$
$\displaystyle \text{side length}=\sqrt{(\Delta x)^{2}+(\Delta y)^{2}}$
$\displaystyle \text{side length} = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

Slope:
$m=\frac{\Delta y}{\Delta x} = \frac{y_2-y_1}{x_2-x_1}$

## Ready to save some money on batteries?

### Let’s say:

You have a TV remote or a small book light that uses three AAA batteries.  The TV remote no longer sends signals to the receiver and the book light does not turn on.  What do you do with the batteries?  Do you roll them around?  Do you rearrange the position of the batteries until the device works?  What if neither of those methods work?

## Caffeine + Low Blood Sugar = Shakiness(Parkinson’s)

As a medically induced diabetic who drinks coffee, I can say this. LOL

Hate Math Love My Glasses by roxagrama

I happened to find this on Deviantart.com. This piece comes from roxagrama on Deviantart.   Although it has an ironic name, I think it shows a nifty perspective through the eyes of a mathematician.  Love it!  I’m curious what the formulas are describing?

## Why Do We Need Math?

I know this is probably more of a reblog but I felt it was really important to show math students and teachers. Carl Sagan makes great points about who will be calling the shots in your life and in the real world when it comes to Science and Technology and this clip is less than 3 minutes long.

## Math – You Haven’t Seen The Last of Me

Hi everyone!  I just wanted to bring your attention to a new page I added to MathyNick.com.  In the Printables tab is a collection of PDF Mathematics handouts/packets that I’ve collected over the years of being a tutor.  Look them over and see if you find any that look like they can help you.
