This is a worksheet that helps to familiarize the student with tangent lines. No knowledge of derivatives is necessary to answer the questions on this worksheet. The student is asked to explore the idea of the tangent line to a graph qualitatively. In addition, the student is asked to draw in a tangent line and approximate its equation using two points on the line.

This worksheet is appropriate for both AP Calculus AB and BC.

An answer key is included.
