Walk through writing a general formula for the midpoint between two points. The midpoint of the points ( x 1 , y 1 ) and ( x 2 , y 2 ) is given by the following formula: ( x 1 + x 2 2 , y 1 + y 2 2 )
Let's practice some geometry problems that can be solved by applying the section formula.

About this unit. In analytic geometry, also known as coordinate geometry, we think about geometric objects on the coordinate plane. For example, we can see that opposite sides of a parallelogram are parallel by writing a linear equation for each side and seeing that the slopes are the same.

Intro to angle bisector theorem. The Angle Bisector Theorem states that when an angle in a triangle is split into two equal angles, it divides the opposite side into two parts. The ratio of these parts will be the same as the ratio of the sides next to the angle. Created by Sal Khan.
Let's explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.
