Properties of Tangents to a Circle

Students will review circle vocabulary (radius, chord, diameter, circumference), learn some new vocabulary (tangent and point of tangency) and learn that a tangent to a circle is perpendicular to the radius at the point of tangency. Students will then solve problems using this circle property. The Which One Doesn't Belong prompt on slide 1 is from Andrew Stadel (@mr_stadel) https://twitter.com/mr_stadel/status/847916623373549569 Nova Scotia Mathematics 9 Outcome M01 - Students will be expected to solve problems and justify their solution strategy, using the circle property that a tangent to a circle is perpendicular to the radius at the point of tangency.
