Instructional Ideas

• Provide pupils with three different lengths of sides and have each build a triangle to show they are all congruent

Classroom Considerations

• The class should know how to find distances on the coordinate plane
• Expects that individuals are familiar with two-column proofs

• This video is hosted on YouTube

Pros

• Works examples using SSS with a proof and on the coordinate plane
• Contains a link to other CK-12 resources on SSS

Cons

• None
