This math topic focuses on the rule for inscribed angles in circles, particularly when one side of the angle forms a diameter. Students are asked to determine the measure of various inscribed angles based on the premise that the line segment forming these angles is a diameter. The consistent theme across the provided problems is understanding and applying the knowledge that an angle inscribed in a semicircle is a right angle. Each question presents multiple-choice answers, where students need to identify the correct degree measure of the angle, usually highlighting the rule that such an angle measures 90 degrees.
