basic introduction into lines, rays, line segments, points, and angles. It also explains the difference between the union and intersection symbols and contains a few practice problems associated with it.
Equation of the normal line at a point
By TheIntegralCALC
http://integralcalc.com/ Learn how to find the equation of the normal line at a given point. To find the equation of the normal line, you'll need to first calculate the derivative of the function, then plug the given point into the derivative to find the slope of the tangent line. Plug the slope and the given point into the point-slope formula for the equation of the line to find the equation of the tangent line. Then take the negative reciprocal of the slope of the tangent line to find the slope of the normal line, which is the line perpendicular to the tangent line. Finally, plug the new slope and the given point into the point-slope formula for the equation of the line to find the equation of the normal line

Point-line distance and angle bisectors | Geometry | Khan Academy
By Khan Academy
Thinking about the distance between a point and a line. Proof that a point on an angle bisector is equidistant to the sides of the angle and a point equidistant to the sides is on an angle bisector
Lines, Rays, Line Segments, Points, Angles, Union & Intersection - Geometry Basic Introduction
By The Organic Chemistry Tutor
Line segments have a beginning and an end and possess a definite length. Angles are composed of two rays that meet at a common endpoint or a vertex.
Inverse Functions | MathHelp.com
By MathHelp.com
In this example, we’re given a relation in the form of a chart, and we’re asked to find the inverse of the relation, then graph the relation and its inverse. To find the inverse of a relation, we simply switch the x and y values in each point. In other words, the point (1, -4) becomes (-4, 1), the point (2, 0) becomes (0, 2), the point (3, 1) becomes (1, 3), and the point (6, -1) becomes (-1, 6). Next, we’re asked to graph the relation and its inverse, so let’s first graph the relation. Notice that the relation contains the points (1, -4,), (2, 0), (3, 1), and (6, -1). And the inverse of the relation contains the points (-4, 1), (0, 2), (1, 3), and (-1, 6). Finally, it’s important to understand the following relationship between the graph of a relation and its inverse. If we draw a diagonal line through the coordinate system, which is the line that has the equation y = x, notice that the relation and its inverse are mirror images of each other in this line. In other words, the inverse of a relation is the reflection of the original relation in the line y = x.
Perpendicular lines from equation | Mathematics I | High School Math | Khan Academy
By Khan Academy
In this video, Sal Khan demonstrates how to know which lines are perpendicular when solving an algebraic equation. (The instructor tells and demonstrates what perpendicular lines are.) Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. (03:28) There is a lot of information on the screen--the viewer may want to open the video to 'full screen.'
