Transcript of "Chapter 3 Notes"

  1. 1. Geometry Warm Up: (not in book) 1. Find the endpoint for the segment that has (9, -3) as one endpoint and (4, -5) as the midpoint. 2. What is the slope of a line containing points (3,4) and (-7, 12)
  2. 2. HW answers pg. 36 1. (3,4) 2. (-9, 1.5) 3. (5.5, 5.5) 4. (-6,44) 5. Yes, add 2 things and divide by 2 is how you get an average 6. (3, 2) and (6, 4) (dividing into 3rd's) 7. find the midpoint and then the midpoint of each half 8. figure 1 (5.5, 6.5) figure 2 (16, 6.75) figure 3 (29.75, 5.5) midpoints are same for the diagonals
  3. 3. HW answers pg. 134 1. -2 2. -12/13 3. 9.7/4.6 or 97/46 or aprrox. 2.1 4. y=23 5. x=4 6. Any point that fits (3p, -4p) such as (6, -8), (9, -12), (12, -16) etc. 7. approx. 66.7 mi/hr 8. skater 1 is 6 m/s skater 2 is 2 m/s, so skater 1 is faster by 4m/s 9. 100% grade for a slope would be 1 (100/100), no 10. adobe house slope is 0 cause flat -conn. steeper b/c snow needs to fall off not pile on. Roof would cave in eventually
  4. 4. Chapter 3 Using Tools of Geometry (speed chapter) D efine the following (words and diagrams) : Answers to gold boxes: 1. Difference between sketch, draw, construct C-5: equdistant 2. Segment bisector C-6: perpendicular bisector 3. Perpendicular Bisector C-7: perpendicular segment 4. Median of a triangle C-8: equidistant 5. Midsegment of a Triangle C-9: meet at a point 6. Equidistant (concurrent) 7. Altitude of a triangle C-10: are concurrent 8. Angle Bisector C-11: are concurrent 9. Concurrent C-12: is equidistant from the 10. Incenter verticies 11. Circumcenter C-13: is equidistant fom the 12. Orthocenter sides 13. Circumscribed C-14: are concurrent 14. Inscribed C-15: twice 15. Centroid C-16: centroid 16. Center of gravity Know these answers: 1. What tools are needded to construct figures? 2. A line segment can be bisected by what 3 things? 3. How many medians and midsegments in three triangles? 4. Altitude is another name for what? 5. How would you construct parallel lines with patty paper? 6. What is the difference between the incenter, circumcenter, orthocenter, centroid? What does each look like in a diagram? (USE OTHER FLIPCHART) 7. How to solve problems # 2-4 pg. 186 8. KNOW what the diagrams look like--incase you have to match them
