These two images relate to geometry because of the way that the square shape is a big key to putting together the measurements in both length and width to form my bedroom ceiling. The same goes for my purse. The squares are basically being substituted for units of measurement in order to bring together my purse and the ceiling.

Arithmetic Mirrors (Abraham)

It looks like you're seeing infinite versions of yourself. This is caused by the light continually reflecting between the two mirrors. Because it takes about two nanoseconds to bounce off the mirror and reach your eye, each version you see of yourself is two nanoseconds older than the previous one. We can use an arithmetic series to find how old is one of those images.

Julia and Bibi Probability exhibit
This exhibit relates to Algebra2 because it illustrates the range of the probability of the marble balls landing in the column.
Sanna,Exhibit: MATHEMATICA: A WORLD OF NUMBERS
1. Probability is a number that describes how likely it is that an event will occur. This image demonstrates mathematics because there is a a standard deviation graph. Which is to square all the numbers in a data set and get your total, divide by the amount of numbers in the data set and minus the mean squared. then square root this number to give you the standard deviation. In this specific graph above, different arrows point at the graph and give examples. Such as pennies laid out equivalent to 10 dollars, with varying weights. different measurements of pencils, burned out light bulbs arranged according to the amount of hours it was lit for.
2. The Critical angle in the image above is related to Snell's law which governs refraction. The process described is transmission with slopping occurrence. It Shows the mathematical relationship between the index of refraction and the amount that light is refracted as it enters the substance.
3. This image above represents a hyperbola which is a set of all points in a plane such that the absolute value of the difference of the distances from two fixed points such as the foci is constant. The variable A represents distance from center to vertex. The variable B represents distance from the center to either side of the rectangle, square, etc, that does not contain a vertex.
