3 12.1 Tangent Lines Warm-up: I can... Identify tangent lines Use the right triangles that result from tangent lines to find missing lengths Homework: 12.1 Page 665 #1-4, 7-9, 11-14, 17, 22 i A tangent to a circle is a line in the plane that intersects the circle in exactly one point. The point of tangency is the point where a circle and a tangent intersect. A 2 1
4 Theorem 12.1-If a line is tangent to a circle, then the line is perpendicular to the radius drawn to the point of tangency. BA is tangent to circle C at point A. Find the value of x. 2
5 A belt fits tightly around two circular pulleys, as shown. Find the distance between the centers of the pulleys. Theorem 12.2-If a line in the plane of a circle is perpendicular to the radius at its endpoint on the circle, then the line is tangent to the circle.?4, 1 le ) 6 3
6 Determine if a tangent line is shown in the diagram. In the picture below, the dashed (blue) circle is inscribed inside the triangle. The solid (red) circle is circumscribed around the triangle. ( What do you notice about the triangle if it circumscribed about a circle? Or, the triangle is circumscribed around the blue circle. 8 4
7 Theorem 12.3-Two segments tangent to a circle from a point outside the circle are congruent. Circle C is inscribed in quadrilateral XYZW. Find the perimeter of this quadrilateral. 5

9 A chord is a segment whose endpoints are on a circle. Theorem 12.4-Within a circle or in congruent circles: 1. Congruent central angles have congruent chords 2. Congruent chords have congruent arcs 3. Congruent arcs have congruent central angles 14 7
10 In the diagram, radius OX bisectszam. What can you conclude? Remind me... how do we describe the distance from a point to a line? 16 8
11 Theorem 12.5-Within a circle or in congruent circles: 1. Chords equidistant from the center are congruent 2. Congruent chords are equidistant from the center 17 9
12 Theorem 12.6-In a circle, a diameter that is perpendicular to a chord bisects the chord and its arcs Theorem 12.7-In a circle, a diameter that bisects a chord (that is not a diameter) is perpendicular to the chord Theorem 12.8-In a circle, the perpendicular bisector of a chord contains the center of the circle 19 P and Q are points on circle 0. The distance from 0 topq is 15 inches and PQ=16 in. Find the length of the radius
13 Find the distance from the center of a circle to a chord 30 m long if the diameter of the circle is 34 m. 21 Two circles intersect and have a common chord 24 cm long. The centers of the circles are 21 cm apart, a length which is perpendicular to the common chord. The radius of one circle is 13 cm. Find the radius of the other circle
14 Two concentric circles have radii 3 and 7. Find, to the nearest hundredth, the length of a chord of the larger circle that is tangent to the smaller circle. 23 I can....
