Circle graphs and central angles
Circle graphs and central angles
What you'll learn
- Identify the central angle and corresponding percentage represented by each sector in a given circle graph with at least 80% accuracy.
- Calculate the measure of a central angle (in degrees) given its corresponding percentage in a circle graph, and vice versa, with 75% accuracy.
- Construct a circle graph from a given set of data, correctly calculating central angles and representing data proportionally, as assessed by a rubric with clear success criteria.
- Explain how a circle graph visually represents data and why the sum of all central angles in a circle graph must equal 360 degrees.
