Below is a link to my Java Sketch. It can be used to explore the properties of tangents of circles.
Tangents of Circles
Students can use this applet to explore properties of tangents of circles. On the sketch students will answer question #1which relate to the properties. Then they will answer question #2, which is a type of question asked on standardized tests.
- Tangents intersect circle at exactly one point.
- At the point of tangency, the angle formed by the radius of the circle and the tangent is a right angle.
- Students can use the Pythagorean theorem to determine if the inscribed angles formed are right angles or not.
