1 Aim: How do we find the measurement of angles formed by tangent, secants, and chords?
Homework: Workbook pg 368 – 369 #’s 1, 4, 6, 7a Do now: find the value of x

2 Definitions Sectants - A line that intersects a circle at two points. Tangents – A line that intersects a circle at one point. Point of tangency - The point of a circle or sphere with a tangent line or plane. Chords – A line that goes from one point on the circle to another point on the circle.

3 Definitions continued
Central angle - A central angle is an angle formed by two intersecting radii such that its vertex is at the center of the circle. Inscribed angle - An inscribed angle is an angle with its vertex "on" the circle, formed by two intersecting chords. Cross chord angles – two chords that intersect to form four angles in which two pairs are congruent.
