Geometry

discover shapes

Understanding what the shape is will help you identify the volume of the object

Equations

These equations make finding the volume easy and fast. click the links to help get started.

Laws

Laws are facts that can not be distributed. Using these criterias you can easily figure out the laws of geometry.

Exponents

Exponents that are positive such as 5^3 is equivilant to 5*5*5. Exponents that are to the zero power allways equal 1 no matter what the base number is.ex) 500^0 = 1^0. For exponents that are negative like 2^-2 all that equals is 1 over 2^2 which is eual to 1/4 or .25.

Solving equations

You first need to balance all equations. So what you do on the right side of the equation you need to do on the left side of the equation. You also want to solve for any variable in the equation. Ex) 0=5x+8 Subtract 8 from both sides of the equation and then divide by 5 on each side to get x=8/5

Graphing equations

when graphing the y=mx+b formula B=the y interecpt and M= the slope of the graph. Always remember if the slope is a fraction use the rise over run formula. For example if the slope is 1/2 You go up 1 and over two. This formula works for negatives as well.

converting tables into a graph

  • First use the equation to make tyhe table.
  • You put in points for "x" to find out what the y value is.
  • After you get at least three different points graph them
  • After graphing them you can use the slope to graph the rest of the points
  • Now you have graphed a line
