  • The question of the day class is, How many degrees equal one interior angle of an octagon?
  • The answer is 1,080
  • That is incorrect, Can anyone help Elizabeth out?
  • We learned in class that an Octagon makes 8 different triangles but also, one triangle equals 180 degrees. An Octagon has 8 sides
  • That is correct Abby but there is something that we're missing. What are we missing?
  • All sums of interior angle of an Octagon equals 1,080. Elizabeth got her answer by doing 180(8-2)=1,080
  • I can  help out Abby to figure out the correct answer. To figure out one interior angle we learned in class to take 1,080degress/8sides. 
  • That makes sense! Thanks for your help Elizabeth! 
  • The correct answer is of one interior angle of an octagon equals 135 degrees. 
  • That is correct Elizabeth. Great job class on the lesson today!
