Students explore the relationships between arcs and angles in these guided inquiry notes and practice. This lesson will help students understand arc measures, so it is a perfect introduction to circle theorems.
• Page 1 guides students through finding arc measures using central angles.
• Page 2 helps students to see the relationship between inscribed angles and arcs.
• Page 3 is a practice worksheet involving unknown central angles, inscribed angles, and arcs. Students must also use knowledge of triangle’s interior angles and linear pairs on this sheet.
I love helping students discovery why formulas work!
Protractors are needed for the first two pages. The third page is not to scale, and students answer questions without a protractor. Answer keys are provided.
