About This Quiz & Worksheet

You can measure inscribed angles by using central angles and arc lengths, and this quiz/worksheet combination will help you understand how to perform these measurements in both ways. These practice questions will ask you to measure inscribed angles using both strategies.

Quiz & Worksheet Goals

The main goal of these assessments is to evaluate your ability to find the measure of an inscribed angle. You will be provided with several diagrams of inscribed circles and given the measures of arcs in the circle. With this information, you will need to use the central angle or arc length strategy to find the correct answer.

Skills Practiced

This quiz and worksheet will help you test your skills in the following areas:

  • Reading comprehension - ensure that you draw the most important information on both inscribed angle measurement techniques from the related lesson
  • Problem solving - use your acquired knowledge to solve inscribed angle measurement practice problems
  • Distinguishing differences - compare and contrast topics from the lesson, such as the two different techniques for measuring these angles
