Students may need assistance when finding coordinates on the unit circle. This tutorial will guide them step by step relying on the Pythagorean Theorem to build the coordinates of any point on the unit circle. Students' familarity with the Pythagorean Theorem will lead them to discover the coordinates of any point on the unit circle when given any x-value or any angle measurement from the vertex at the origin.
Before the Activity
Students should have already been introduced to the unit circle and its basic characteristics. The Pythagorean Theorem should be a basic tool already mastered.
During the Activity
Students should work alone or in pairs to complete the activity.
