Presentation Transcript

• Name the intersection of plane AEH and plane GHE.

• What plane contains points B, F, and C?

• What plane contains points E, F, and D?

• Postulate 1.5 – Ruler Postulate

• Every point on a line can be paired with a real number.

• The real number that corresponds to a point is called the coordinate of the point.

• Allows you to measure lengths of segments and will allow you to find the distances between points.

• The distance between points A and B is the absolute value of the difference of their coordinates.

• What is ST?

• What is SV?

• What is UV?

• What is TV?

• ST = | -4 – 8 | = | -12| = 12

• SV = |-4 – 14 | = | -18| = 18

• UV = | 10 – 14| = | -4| = 4

• TV = |8 – 14| = | -6 | = 6

• If three points A, B, and C are collinear and B is between A and C, then AB + BC = AC.

• If EG = 59, what are EF and FG?

EF + FG = EG

(8x – 14) + (4x + 1) = 59

12x – 13 = 59

12x = 72

x = 6

EF = 8(6) – 14 = 34

FG = 4(6) + 1 = 25

• The midpoint of a segment is a point that divides the segment into two congruent segments.

• A point, line, ray, or other segment that intersects a segment at its midpoint is said to bisect the segment.

• The point, line, ray, or segment is called a segment bisector.

B

• Q is the midpoint of PR. What are PQ, QR, and PR?

• Find x.

6x – 7 = 5x + 1

x – 7 = 1

x = 8

Find PQ and QR.

PQ = 6x – 7

= 6 ( 8 ) – 7

= 41

Find PR.

PR = PQ + QR = 41 + 41 = 82.
