Today we learned about sector area using our understanding of proportions and circumference!
Practice p. 39-40 Homework p. 41-44 After our quiz, we developed the equation for arc length and used algebra to solve for radius and measure of central angle.
Practice p. 35-36 Homework p. 37-38 Today we did a soft review for our quiz tomorrow. Attached is the key for the review and some extra practice to check yourself!
Practice p. 32-34 Extra Practice p. 26-31 Happy Valentine's Day! After presenting our projects, we practiced finding angles inside and outside of circles. Below is a fantastic proof of vertical angles of intersecting chords being equal to the sum of half of the intercepted arcs!
Practice: Review Chains (create math chains by linking problem with its solution) Half of Sum Proof: www.youtube.com/watch?v=TB7-uZWnS9g Another Half of Sum Proof: www.youtube.com/watch?v=BJMMir183r0 Half of Difference Proof: www.youtube.com/watch?v=hvFQxb4o6H0 Today students practiced finding angles inside and outside circles made by chords, secants, and tangents. Attached is the answer key to check the practice!
Angles of Circles Video (the first 20 minutes): www.youtube.com/watch?v=Ulr8-27TZgc Circle Vocab Project Due Tomorrow! Today we took our vocab quiz after a little review. We added to yesterday's lesson on inscribed angles to include inscribed right triangles and quadrilaterals.
Practice p. 22-23, 18-19 Homework p. 20-21 Vocab Projects are due Friday! Today we built upon yesterday's lesson to include inscribed angles (vertex on the circle). Our vocab quiz is tomorrow!
Practice p. 11-13 Homework p. 14-17 Central Angle Theorem/Inscribed Angle Relationship www.mathopenref.com/arccentralangletheorem.html Today we began Unit 3 with circle vocab and solving problems with central angles. We also received a project describing circle vocabulary, which will be due Friday, February 14.
The end of the first six weeks is this Friday. Please make sure to take any missing test/quiz this Wednesday or Thursday! Practice p. 3-7 Homework p. 8-10 |
