PLSSS HELP!!!! URGENT!!!!!!!!!!! Jamie says that if she knows only the measure of one angle in an isosceles triangle, she can always determine the measures of the other two angles. Denise disagrees with her.
Who do you think is correct, Jamie or Denise?
Explain your reasoning. Include specific examples to support your answer.

Jamie is correct. Either she knows one of the two equal angles, and thus just needs to do 180 - 2(the angle she knows) to get the other angle. OR Jamie knows the single angle in the isosceles triangle, and just needs to subtract it from 180 and divide the result by 2 : )
1) I think Jamie is correct.
2) The reason Jamie is correct is because if we know one angle of an isosceles triangle then we just have to add up to the total of 180. If we know of of the two equal angles then we can just multiply the angle we know and then subtract it from 180 to find the other angle and if we know the third angle which is not a part of the congruent angles then we can just subtract is from 180 and divide it by two to find the two congruent angles.
