  6. Midpoint Theorem and Coordinate Proof Section 5.1

  7. The Concept • This chapter covers some very important theorems and properties of triangles • These theories will aid us in our introductory exploration of trigonometry in Chapter 7

  8. Theorem 5.1: Midsegment Theorem The segment connecting the midpoints of two sides of a triangle is parallel to the third side and is half as long as that side Theorem How could we show this? midpoint midpoint A B A B

  9. Example

  10. Find AB, if A & B are midpoints Example 3x+8 B A 2x+24 G J

  11. Coordinate Proof Process of placing a geometric figure on the coordinate plane and then using variables to represent the coordinates to prove various statements Definition (k,h) (2k,0)

  12. Example

  13. Homework 5.1 Exercises 1-11, 12-18 even, 24-28 even, 33-39 odd

  14. Prove that Triangle PQR is isosceles Example P (0,k) Q (-h,0) R (h,0)

  15. Midpoint Theorem • Placing a geometric figure on the coordinate plane Most Important Points
