MAFS.912.G-SRT.2.4: Prove theorems about triangles. (Theorems include: Triangle Proportionality Theorem or Side Splitter Theorem – a line parallel to one side of a triangle divides the other two proportionally.)
|Learning Targets and Learning Criteria|
- define geometric mean.
- find measures in similar right triangles using geometric mean.
- apply theorems, postulates, or definitions to prove theorems about triangles, including proving The Pythagorean Theorem using triangle similarity.
- We will watch a video on Geometric Mean
- We will watch the Section 7, Topic 6 video on Geometry Nation (Right Triangles Similarity–Part 1)
- We will watch a YouTube video (Triangles: Similar Right Triangles, Geometric Mean) to understand the Right Triangle Altitude Theorem)
- Students will do a Geometric Mean maze
- We will review the Altitude Rule and the Leg Rule for the Geometric Mean Theorem
- Students will do IXL P-New (Similarity and Altitudes in Right Triangles)
- Students will do Section 7, Topic 1 in Geometry Nation, writing down notes and will put this page in their ISN
- Students will then do Section 7, Topic 6 and Section 7, Topic 7 in the Geometry Nation Practice book on pages 132-134 (just #5 on page 134)
- Students can finish the IXL if they complete the workbook pages
- Section 7, Topic 6 of Geometry Nation should be complete and in ISN by January 10.
- Section 7, Topic 1 of Geometry Nation should be complete and in ISN by January 10.
- IXL P-New (Similarity and Altitudes in Right Triangles) due by January 10.
