We went over the homework together and then completed our quadrilaterals chart by talking about the unique properties of kites today. We then went over one more parallelogram proof together before getting started on the review sheet. Chapter 5 Test will be on Monday, Nov. 23

14. rectangle
15. angle WXY is congruent to angle WZY
16. WX is parallel to ZY or WZ is congruent to XY
17. WX is parallel to ZY or WZ is congruent to XY
18. ZP is congruent to PX
19. Drawing the quadilateral and drawing in an auxiliary line between ZX to form two triangles is necessary to fully understand the proof.
Statements Reasons
angle XWZ congruent to angle XYZ given
WX parallel to ZY given
angle WXZ congruent to angle XZY if lines parallel, AIA congruent
ZX congruent to ZX reflexive
triangle XWZ congruent to triangle ZYX AAS
WX congruent ZY CPCTC
WXYZ is parallelogram If one pair of opp. sides are both
congruent and parallel, then quad,
is parallelogram
