Angle Bisector Theorem	Geometry	The angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle.	View
Box Rotation around a Point	Geometry	Graph demonstrates how to rotate a box around a point using trigonometry.	View
Building Equations from Rectangles	Equations	Pre-Algebra: Build equations by turning on width or height and area. Or build equations by turning on width or height and perimeter. Algebra 1: Build and solve a quadratic equation by turning on area and perimeter.	View
Calculating Correlation Coefficient	Statistics	Graph helps visualize the correlation coefficient relationship between two variables.	View
Calculating Pi with Calculus	Calculus	Pi may be calculated by finding the area under a half-circle, then solving for pi using the area of a circle.	View
Calculating Pi with Perimeter	Number Theory	π may be calculated by inscribing a regular polygon into a circle. By measuring perimeter, π may be estimated.	View
Calculating Sample Variance and Standard Deviation	Statistics	Variance measures how far a set of numbers is spread out from their average value. This model represents the calculation of sample variance.	View
CAMPARING EXPRESSIONS AND EQUAIONS	Geometry	What is a numerical expression? A numerical expression is (7+9) 5. The difference between expressions and equations is that expressions only have the numbers and equations answer the expressions. for example: (7+9) 5 - expression (7+9) *5= 80 - equation. Even though they are different they are also the have some similarity they both have operations, variables, and numbers (obvious).	View
Circumcenter Theorem	Geometry	Any point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment.	View
Color Theory (CMYK)	Geometry	Any color you see on a surface is formed by the subtractive color mixing model. We are more familiar with this color model because it is how we learned to mix colors. In this case, “subtractive” refers to removing the light from the paper by adding more color. "K" represents blacK which is added in the printing process to make the colors more realistic.	View
