Special Angle Relationships Angles <3 & <6 <4 & <5 <3 & <5 <4 & < Angles <2 & <6 <3 & <7 <1 & <4 <6 & <7

Special Angle Relationships WHEN THE LINES ARE PARALLEL Alternate Angles are CONGRUENT Vertical Angles are CONGRUENT Co-Interior Angles are SUPPLEMENTARY Corresponding Angles are CONGRUENT If the lines are not parallel, these angle relationships DO NOT EXIST.

9
Lets Practice m<1=120° Find all the remaining angle measures ° 120°

10
Another practice problem Find all the missing angle measures, and name the postulate or theorem that gives us permission to make our statements. 40° 120°
