1. EMPTY folders- put papers in your binders. ONLY keep weekly warm up sheet and current day’s classwork in folders. Warm-up- silently please REVIEW SLIDES pg. 245: 1-3 include sketch and given information (as always!) Honors Geometry 28 Nov 2011

2. altitude the perpendicular segment from a vertex to the opposite side or a line containing the opposite side

3. midsegment- the segment that connects the midpoints of two sides of a triangle midsegment

4. median- the segment connecting the vertex of a triangle to the midpoint of its opposite side median

5. Review Symmetry Line in An Isosceles Triangle Vertex Angle Bisector Conjecture: In an isosceles triangle, the bisector of the vertex angle is also a median and an altitude. bisector median altitude 12 A B C D

6. Objective Students will learn the definitions of special quadrilaterals and explore the sum of exterior angles of a polygon. Students will take notes, do an investigation and apply properties to solve problems.

7. DUE Tuesday, Nov. 29: Finish Handout 4.8 Proving Special Triangle Conjectures (need a copy? see DG4 PYSA link to PDF on my wiki page) Due Wed/Th, Nov. 30/Dec 1 pg. 260: 6 – 8 pg. 264: 5 – 8, 16

8. review polygon vocab sketch on back of handout and label: side, vertex, diagonal, consecutive sides, consecutive vertices see page 54

9. special quadrilaterals see page 64 - 65 Fill in graphic organizer as we go over the definitions as a class on back or on separate paper DO pg. 66: 2 - 10

10. debrief what did you learn today? what math did we do?
