Proving Lines Parallel


By Pete Anderson

A teacher goes over a number of examples reviewing some of the previously learned theorems and then applies them to proving that lines are parallel.

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!

Triangle Similarity - AA SSS SAS & AAA Postulates, Proving Similar Triangles, Two Column Proofs


By The Organic Chemistry Tutor

This geometry video tutorial provides a basic introduction into triangle similarity. it explains how to use two column proofs in order to prove if two triangles are similar using the mostly the AA postulates. Other triangle similarity postulates mentioned are the AAA, SSS, and SAS postulates. Theorems used in this video include the base angle theorem, theorems associated with parallel lines, alternate interior angle theorem, vertical angles, reflexive property, definition of an altitude, right angle congruence, and more. This geometry video contains plenty of examples and practice problems on triangle similarity.

The Life Autistic Documentary


By Lumos Learning

Iowans with autism illustrate the nuances of The Life Autistic in this two-hour broadcast special. We meet twelve people of different ages and backgrounds, along with their families and caregivers, to understand the daily lives and future prospects of people with autism. Their stories explore diagnosis, early intervention, family life, treatment, education, employment and independent living. Interviews with experts, educators and advocates -- including famed author and speaker Temple Grandin -- provide greater context and a better understanding of the many expressions of autism. Tyler Leech lends his unique perspective as a member of Iowa’s community of people with autism to the stories from the original Iowa PBS web series.
