MAFS.912.G-SRT.3.8: Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
|Learning Targets and Learning Criteria|
- use Special Right Triangles (30°-60°-90° and 45°-45°-90°) to solve for missing side lengths.
- use angle measures to estimate side lengths and vice versa.
- solve right triangles by finding the measures of all sides and angles in the triangles using Pythagorean Theorem and/or trigonometric ratios and their inverses.
- draw right triangles that describe real world problems and label the sides and angles with their given measures.
- solve application problems involving right triangles, including angle of elevation and depression, navigation, and surveying.
- I will introduce Special Right Triangles and their connection to Triangle Similarity
- We will do the first two pages of a packet on 45-45-90 Triangles together
- Students will complete the practice pages of the 45-45-90 packet independently
- We will do the first three pages of the 30-60-90 Triangles packet together
- I will go over a few problems from the IXL on Geometric Mean to help students who struggled with that.
- Students will complete the practice pages of the 30-60-90 Triangles packet.
- Students will do IXL Q.4.
- Students will finish the IXL P-New on Geometric Mean.
- Practice Problems on 30-60-90 Triangles packet due January22.
- IXL P-New due January 22.
- IXL Q.4 due January 22.
