Geometry - Semester 2 Mrs. Day-Blattner 2/24/2017 Agenda 2/24/2017 1) 2) 3) 4) Bulletin Quiz Circles Lessons 1-4 Page 39 “Lesson 4” Experiments with Inscribed angles Homework Geometry Circles Quiz Test Seats - OK to have something to do when finished. Calculators are allowed, but no other electronic devices. Turn cell phones off and leave them in backpacks. Estimate: 45 minutes for the quiz. Our Lesson 6. Page 39 Lesson 4. Experiments with Inscribed Angles. Draw this diagram at the top of the page. B C A F E Use this diagram and the Lesson Summary on page 41 and your textbook to describe and explain all the terms on page 39. Homework. Problem Set, starts on page 41 Complete 1, 2, 3, 4, and 5. Explain all your thinking. Write neatly and in an organized way. Use the diagram to help you identify the following terms: Arc Minor and major arc inscribed angle central angle intercepted arc of an angle Use the diagram to help you identify the following terms: Arc An arc is a portion of the circumference of a circle Use the diagram to help you identify the following terms: Minor and major arc BE is a minor arc EDB is a major arc What’s the difference? Use the diagram to help you identify the following terms: inscribed angle Angle BDC is an inscribed angle angle whose vertex is on the circle, and each side of the angle intersects the circle in another point. Use the diagram to help you identify the following terms: Central angle angle BAC is a central angle An angle whose vertex is the center of the circle. Use the diagram to help you identify the following terms: intercepted arc of an angle angle CDB and angle CAB both intercept arc BC . What do you think it means for an angle to intercept an arc? Use the diagram to help you identify the following terms: intercepted arc of an angle An angle intercepts an arc if the endpoints of the arc lie on the angle, all other points of the arc are in the interior of the angle, and each side of the angle contains an endpoint of the arc.
