Ch 7: Similar Polygons: Homeschool Curriculum

About This Chapter

The Similar Polygons unit of this High School Geometry Homeschool course is designed to help homeschooled students learn about using angles and sides to identify similar polygons. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our High School Geometry Homeschool course will benefit any student who is trying to learn about using angles and sides to identify similar polygons. There is no faster or easier way to learn about similar polygons. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about the properties of triangles and to solve problems that involve proportions.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a math curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and the Similar Polygons unit exam confirm understanding or identify any topics that require review.

Similar Polygons Unit Objectives:

  • Find the transitive property of similar triangles.
  • Learn about proportional segments.
  • Identify the properties of right triangles.
  • Explain the angle bisector theorem.
  • Provide examples of the triangle proportionality theorem.
  • Learn to apply the Pythagorean theorem.
  • Prove special cases and the converse of the Pythagorean theorem.
  • Establish the criteria for two triangles to be similar.
