Adjacent Vertical Supplementary and Complementary Angles Adjacent angles Slides: 41 Download presentation Adjacent, Vertical, Supplementary, and Complementary Angles Adjacent angles are “side by side” and share a common ray. 45º 15º These are examples of adjacent angles. 80º 45º 35º 55º 85º 130º 20º 50º These angles are NOT adjacent. 100º 50º 35º 55º 45º When 2 lines intersect, they make vertical angles. 75º 105º 75º Vertical angles are opposite one another. 75º 105º 75º Vertical angles are opposite one another. 75º 105º 75º Vertical angles are congruent (equal). 150º 30º 150º Supplementary angles add up to 180º. 40º 120º 60º Adjacent and Supplementary Angles 140º Supplementary Angles but not Adjacent Complementary angles add up to 90º. 30º 40º 60º Adjacent and Complementary Angles 50º Complementary Angles but not Adjacent Practice Time! Directions: Identify each pair of angles as vertical, supplementary, complementary, or none of the above. #1 120º 60º #1 120º 60º Supplementary Angles #2 30º 60º #2 30º 60º Complementary Angles #3 75º #3 Vertical Angles 75º #4 40º 60º #4 40º 60º None of the above #5 60º #5 60º Vertical Angles #6 135º 45º #6 135º 45º Supplementary Angles #7 25º 65º #7 25º 65º Complementary Angles #8 90º 50º #8 90º 50º None of the above Directions: Determine the missing angle. #1 135º 45º #2 25º 65º #3 35º #4 130º 50º #5 140º #6 50º 40º Types of angles and their namesVertical supplementary anglesAdjacent and complementary anglesComplementary and supplementary angles formulaAngle 1 and angle 2 are supplementaryNon adjacent supplementary anglesLinear pairVertical angles are congruentVertical anglesDescribe adjacent anglesVertical anglesComplementary linear pair vertical or adjacentVertically opposite angles propertiesTwo nonadjacent angles formed by 2 intersecting linesAngles a and b are complementaryDiagonal theorem parallelogramAngle word problemsReal world examples of anglesSupplementary angles definitionAlternate anglesVertical congruent anglesWhat are congruent trianglesExample of supplementary anglesConsecutive interior anglesCorresponding anglesAcute angle definitionSupplementary angles transversalSupplementary angles on transversalHorizontal strategic allianceVertical anglesSegment addition postulateWhich relationships describe the angle pair x° and 50º?Reflection geometry in real lifeAn angle supplementary to cbfNon adjacent anglesLine and angleAdjacent in geometryAdjacent anglesSohcahtoaWhat angle is thisPictures of vertical anglesAdjacent angles
