This is important. en-us 2020-09-11 18:23:34 UTC 2025-09-24 18:25:07 UTC hello@padlet.com When two PARALLEL LINES are cut by a TRANSVERSAL, 8 angles are created. calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/739989283 2020-09-11 18:27:22 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/739989283 4 of the angles are ACUTE and the other 4 are OBTUSE. calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740012010 Would you agree that...
   Angle 1, 3, 5 and 7 are ACUTE
   Angle 2, 4, 6 and 8 are OBTUSE]]> 2020-09-11 18:33:04 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740012010 Also, the angle pairs on this diagram will either be... calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740023444      1.  CONGRUENT (the same)
     2.  SUPPLEMENTARY  (=180)]]> 2020-09-11 18:35:53 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740023444 ACUTE OR OBTUSE? calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740031454
All of the PURPLE RED angles are ACUTE!

All of the GREEN angles are OBTUSE!]]> 2020-09-11 18:37:50 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740031454 How will we set up our equations? calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740109907 2020-09-11 18:59:24 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740109907 How can we tell if the angles are CONGRUENT or SUPPLEMENTARY? calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740115800
CONGRUENT:  (Part = Part)
     Acute = Acute
     Obtuse = Obtuse

SUPP:  (Part + Part = 180)
     Acute + Obtuse = 180]]> 2020-09-11 19:01:17 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740115800 Now for 4 Example Problems... calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740127804 2020-09-11 19:05:17 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740127804 Let's Summarize... calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740252634 2020-09-11 19:49:52 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740252634 Example 1 calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740291274 2020-09-11 20:06:24 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740291274 Example 2 calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740304230 2020-09-11 20:12:09 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740304230 Example 3 calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740326125 2020-09-11 20:22:09 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740326125 ONE MORE... calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740333510 2020-09-11 20:25:46 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740333510 Example 4 calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740340356 2020-09-11 20:28:45 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740340356 calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740357827 IS YOUR HEAD SPINNING??!!]]> 2020-09-11 20:36:45 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740357827 Of course not... This is simple! calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740359036
ACUTE = ACUTE
OBTUSE = OBTUSE
ACUTE + OBTUSE = 180]]> 2020-09-11 20:37:24 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/740359036 Click on the Activity below to practice classifying angles as CONGRUENT or SUPPLEMENTARY. calford10 https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/741412482 2020-09-13 02:35:15 UTC https://padlet.com/calford10/7r9ybbo9xu4n69vl/wish/741412482
