Angles of Parallel Lines - Khan Academy
By Khan Academy
Angles of a transverse line when you intersect parallel lines are discussed in this video. Video discusses parallel lines and what a transverse line is. Video then goes into labeling the angles, such as corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The video shows how to find the measurement of each of the angles using what you know about angles and lines. Good review for concepts of angles and vocabulary associated with angles. Good quality video. Good for middle elementary and middle school students.
Parallel and Perpendicular Lines, Transversals, Alternate Interior Angles, Alternate Exterior Angles

parallel and perpendicular lines in addition to transversals and all the angles that are formed by it such as alternate interior and exterior angles.

Angles (part 3) | Angles and intersecting lines | Geometry | Khan Academy
By Khan Academy
This video uses an electronic black board with different colored pens. Angles formed with two parallel lines (defines parallel lines) and a transversal line (a line that crosses the two parallel lines). The video then goes into labeling the various angles, corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The last thing the video explains is that all the angles in a triangle add up to 180 degrees. It shows how to find the measurements of each of these angles. Good video for review of concepts and angle vocabulary. Good for middle school students.

Flipped Classroom Lines and Angles
By Megan Priole
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines.
Algebra 1 Help | MathHelp.com
By MathHelp.com
This lesson covers parallel lines. Students learn that if two parallel lines are cut by a transversal, then corresponding angles are congruent, alternate interior angles are congruent, and same-side interior angles are supplementary. Students are then asked to find missing values based on these concepts.

8.5 Three Theorems Involving Proportions (Lesson)
By AutenMath
A lesson on the Angle Bisector and Side Splitter theorems and a theorem relating segments cut by two transversals and three or more parallel lines.
Find missing angles of triangles
By Khan Academy
Sal combines what we know about isosceles triangles and parallel lines with the power of algebra to solve the angles of an isosceles triangle.
Angle bisector theorem proof | Special properties and parts of triangles | Geometry | Khan Academy
By Khan Academy
In this video, we'll quickly review the angle bisector theorem, and then we'll see how it's proven. We prove it by extending a parallel line to one of the triangle's legs. That tells us information about the interior angles!
Proving the Sum of Measures of Angles in a Triangle are 180
By Khan Academy
This video gives us a walkthrough of the proof that the angle measures of the angles of a triangle add up to 180. This proof requires us to draw in a line on our own (specifically, one that is parallel to one side of the triangle, but it could be any side). Then we can treat the two non-parallel sides as transversals.
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.
