  1. Warm up Use Pythagorean Theorem to find the missing side. Round to the nearest tenths. 8.2 yd Good morning!! 8.3 m 2.2 ft

  2. HW Answers Practice HW 1. arc AB 1. a. angles DOC, BOC, BOA, AOD 2. arc ADB b. Arcs AB, ABC, AD, DC 3. arc PSQ c. many 4. 63 deg d. Arc BAD or BCD 5. 117 deg e. AB, BE, BD 6. 130 deg f. Angle AOD 7. 140 deg 2. 30 deg, 150 deg 8. 75 deg 3. 125 deg, 227 deg 9. 225 deg 4. 67 deg, 203 deg 10. 120 deg 5. 70 deg, 200 deg 11. 270 deg 6. 125 deg 12. 120 deg 7. 102 deg, 82 deg

  3. TANGENTS A line is tangent to the circle only if it is perpendicular to the radius drawn to the point of tangency

  4. Is AD tangent or not tangent? No, point D is not tangent to the circle.

  5. Is AB tangent or not tangent?Use Pythagorean Theorem to find out. Yes 682 + 512 = 852

  6. Is AB tangent or not tangent?Use Pythagorean Theorem to find out. No 82 + 162≠ 192

  7. Solve for x. x2 + 962 = 1002 x = 28 BC is a radius of Circle C AB is tangent to Circle C

  8. Solve for x. x2 + 482 = 802 x = 64 BC is a radius of Circle C AB is tangent to Circle C

  9. Common External Tangents Common Tangents A line that is tangent to more than one circle is referred to as a common tangent. Both lines k and j are common tangents. j k

  10. Common internal tangents Common Internal Tangents Common internal tangents intersect the line that connect the center of the circles whereas common external tangents do not intersect that line. Both line j and line k are common internal tangents.

  11. Tangent Lines Congruent Tangent Lines Theorem: If two segments from the same exterior point are tangent to a circle, then they are congruent. Name the congruent segments above!

  12. Party Hat Problems(Tangent/Tangent)

  13. S Party hat problems! If two segments from the same exterior point are tangent to a circle, then they are congruent. R T

  14. Solve for x

  15. Solve for x

  16. Solve for x C P

  17. Find NP N T S P R Q

  18. Homework Class work If on task, no HW this weekend!!! Big IF!
