2. A C B  <ABC =30 0 & <CBD = 35 0 Then <ABD = ? B C D A B D

3.  IfAB = 10 and BC =15 then AC =? A B B A C C

4.  Acute angles are angles that have a measure greater than 0 0 and less than 90 0  Obtuse angels are angles that have a measure greater than 90 0 and less than 180 0  Right angles are angles that measure 90 0  Straight angles are angles that measure 180 0 (a line)

5.  Made up of two axis; x-axis (horizontal) & y- axis (vertical)  Axis intersect at the origin (0,0)  Breaks up a two dimension space into quadrants. Numbered 1-4.  Each point corresponds to an ordered pair (x,y)

6.  The distance d between two points A(x 1,y 1 ) and B(x 2,y 2 ) is  d=√(x 2 -x 1 ) 2 + (y 2 -y 1 ) 2  Find the distance between (-3,4) (8,-6) & (4,8) (2,3)

7.  Vertical angles - What are they?  Angle Bisector – What is it?  Perpendicular bisector – What does it do?
