SSS Similarity Theorem: Lesson
2 mins 9th - 11th CCSS: Adaptable
New ReviewJudging by the sides, things appear similar. A portion of a larger playlist on geometry introduces the Side-Side-Side Similarity Theorem. The video shows how to use the lengths of sides to determine whether triangles are similar.
Comparing Triangle Angles and Sides: Lesson
5 mins 7th - 11th
Use the opposite to organize angles or sides. The video provides the relationship of angle measures based on the lengths of sides in a triangle and its converse. Using two triangles, the segment of a larger playlist on geometry shows the...
ASA and AAS Triangle Congruence Lesson
4 mins 8th - 11th CCSS: Adaptable
The location of the side makes a difference. One of the videos in a geometry playlist introduces angle-side-angle and angle-angle-side congruence relationships. Using drawings, the video shows how these two congruence statements are...
SAS Triangle Congruence: Lesson
3 mins 8th - 11th CCSS: Adaptable
SAS is not just a spy organization. A section of an extensive geometry playlist introduces a way to show two triangles are congruent, SAS. Using diagrams, the video provides an explanation by showing only one triangle is formed with two...
Classifying Polygons: Lesson
4 mins 4th - 8th CCSS: Adaptable
For your eyes only: classify the names of polygons. After providing the definition of a polygon, the video introduces the two major classifications of polygons, concave and convex. The segment of a larger playlist on geometry continues...
Geometer Sherlock: Triangle Investigations
8th - 10th CCSS: Designed
Deduce quite elementary relationships within triangles. Small groups work through three investigations of triangles. The investigations use patty paper to determine the Triangle Sum Theorem and the relationship between the angle size and...
Proofs: Angle Pairs and Segments—The Three Angle Problem
9th - 11th
Finding the sum of the measures of three angles is easy, unless you have no clue what the measures are. Learners use an interactive diagram to see a geometric problem in a different way. A set of challenge questions takes them through...
SOHCAHTOA - Finding Missing Sides Part 2
3 mins 9th - 12th CCSS: Adaptable
Explore some right triangle trigonometry with a straightforward video lesson. The instructor presents problems requiring scholars to use trig ratios to find unknown side measures. She provides worked-out solutions for those needing...
Special Triangle Ratios: Special Right Triangle Ratios
9th - 12th CCSS: Designed
Go from one side length to any other side length with special right triangles. Individuals use the interactive to investigate the ratio of sides in 45-45 and 30-60 right triangles. Scholars make generalizations about the types of special...
