Bell Work: Definitions Copy all of the terms below into your review book on page 3! Point - names a location, has no size. Line – straight path with no thickness-extends forever Plane- a flat surface with no thickness Coplanar- points that lie in the same plane Skew- non-intersecting, non-parallel lines Ray-part of a line with one endpoint. Segment-part of line with two endpoints.
Match term with defenition 1. Congruent 2. Adjacent Angles 3. Complimentary 4. Two planes intersect in a 5. Opposite Rays (A) Two rays that share an endpoint (B) Two angles whose sum is 90. (C) Same size (D) Two Angles that share a ray (E) Line

Solve-show all your work Make sure to draw a diagram. C is between A and E. If AC = 24 in. and CE = 13 in., AE = _____
Draw this diagram on your notes Identify the following: Intersection of planes ADC and GDC Two parallel lines Two parallel planes
Find MN if N is between M and P, MN = 3x + 2, NP = 18, and MP = 5x. 3x + 2 18 M P N 5x MN = 3 (10 ) + 2 MN = 32 3x + 2 + 18 = 5x 3x + 20 = 5x -3x -3x 20 = 2x 2 2 10 = x
Given: m<RSV = x + 5 M<VST = 3x – 9 M<RST = 68 Find x. R V Extension: Now that you know x = 18, find m<RSV and m<VST. m<RSV = x + 5 m<RSV = 18 + 5 = 23 m<VST = 3x – 9 m<VST = 3(18) – 9 = 45 Check: m<RSV+ m<VST= m<RST 23+ 45 =68 S T Set up an equation using the Angle Addition Postulate. m<RSV+ m<VST= m<RST x + 5 + 3x – 9 = 68 4x- 4 = 68 4x = 72 x = 18 Plug in what you know.
