#### SSS Similarity Theorem: Lesson

Judging 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.

Lesson Planet: Curated OER

#### Parallelograms: Lesson

Properties spawn from parallel sides. With the aid of diagrams, the presentation shows the different properties of parallelograms. The segment of an extensive geometry playlist lists the properties that using the parallel sides of a...

Lesson Planet: Curated OER

#### Comparing Triangle Angles and Sides: Lesson

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...

Lesson Planet: Curated OER

#### ASA and AAS Triangle Congruence Lesson

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...

Lesson Planet: Curated OER

#### SSS Triangle Congruence: Lesson

Gimme three sides, mister! The video introduces the Side-Side-Side Triangle Congruence Theorem. Using segments of different lengths, the portion of a larger playlist on geometry shows that only one triangle can be built.

Lesson Planet: Curated OER

#### SAS Triangle Congruence: Lesson

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...

Lesson Planet: Curated OER

#### Classifying Polygons: Lesson

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...

Lesson Planet: Curated OER

#### Proofs: Angle Pairs and Segments—The Three Angle Problem

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

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...

Lesson Planet: Curated OER

#### The Pythagorean Theorem

Be sure the class gets this one right. Using a right triangle, the video introduces the Pythagorean Theorem. The presentation breaks down the theorem into its components while providing uses of the Pythagorean Theorem and its converse.

Lesson Planet: Curated OER

#### Polygons

What shapes classify as a polygon? The resource provides the definition of a polygon and provides examples of polygons and shapes that are not polygons. The presentation gives an explanation of why each shape falls into the particular...

Lesson Planet: Curated OER

#### Special Triangle Ratios: Special Right Triangle Ratios

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...

Lesson Planet: Curated OER

#### Polygon Angle Sum

Using patterns to build a formula is an important mathematical skill. Pupils discover a formula to find the sum of interior angles in a polygon by analyzing a pattern. The additional videos show how to use the formula to find various...
