  2. Midsegment Theorem and Coordinate Proof

  3. parallel half 90 in 45 in .5 .5 2 2 45 in 90 in

  4. Check Point #1

  5. midpoint midpoint midsegment Midsegment theorem

  6. Check Point #2 Then SV is the midsegment of triangle QRP.

  7. Coordinate Proofs • A coordinate proof is a proof that uses the coordinate plane to help prove items • It will also use definitions, postulates, and theorems to prove the said item

  8. 2(4x + 5) = 3x + 25 8x + 10 = 3x + 25 5x +10 = 25 5x = 15 x=3

  9. 2(2x + 7) = 5x – 1 4x + 14 = 5x – 1 14 = x – 1 15 = x

  10. Crossbar would form the midsegment, therefore the crossbar is half the length of the distance between the two legs. Therefore the distance between the two legs is 72 inches.
