Recognizing parallel and perpendicular lines
By Khan Academy
Do the two lines intersect or stay apart? If they intersect, do they do so thereby creating a 90 degree angle? These are the kinds of questions we ask ourselves when we learn about parallel and perpendicular lines.

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.'

Let's now apply what we learned and do an exercise together in which we identify parallel and perpendicular lines.This is great practice.
Surface Area of a Pyramid | MathHelp.com
By MathHelp.com
This lesson covers the definition of perpendicular lines. Students learn the definition of perpendicular lines and use algebra to find the measures of angles in problems that involve perpendicular lines. Students are also asked to determine whether given information is sufficient to determine if two lines are perpendicular.
Flipped Classroom Lines and Angles
By Megan Priole
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines.
Step-By-Step Instructions for Geometric Constructions
By Ezlie
This video gives us each step of the essential geometric constructions. The first part of this video goes through some important geometric vocabulary (parallel lines, midpoint, etc), so you may want to skip ahead to 1:30 to get to the constructions. Constructions in this video: Copying a line segment Construcing the perpendicular bisector of a line segment Constructing a perpendicular to a line through a point not on the line. Constructing a perpendicular to a line through a point on the line. Bisecting an angle Copying an angle
