1. Day 1 I can apply the transitive properties of angles & segments. I can apply the substitution property. I can recognize vertical angles.

2.  Equal quantities may replace each other Substitute x = 14 into <A = 2x – 4 If <1 is comp. <2 <2 ≅ <3

3.  If angles (segments) are congruent to the same angle (segment) or congruent angles (segments), then they are congruent.  Special type of substitution ACE If <A ≅ <C <C ≅<E then NAD TMO If TO ≅ OM DA ≅ AN OM ≅AN then

4.  Opposite rays- two collinear rays that have a common endpoint and extend in opposite directions ABC but not AB C

5.  Vertical Angles: A pair of non-adjacent angles formed by the intersection of two straight linesadjacent anglesintersection  Thm: Vertical angles are congruent 1 4 3 2 ∠1 and ∠3 are vertical angles ∠2 and ∠4 are vertical angles

6.  Given: m∠1=37˚  Find: m∠2, m∠3, m∠4 1 4 2 3

7.  Given: ∠4≅∠6  Prove: ∠5≅∠6 5 6 4

8.  Given: ∠V≅∠YRX, ∠Y≅∠TRV  Prove: ∠V≅∠Y T XY R V

9.  Is this possible? (-10x)˚ (-8x-10)˚
