Will fan and Medal
Draw a triangle that is both a right triangle and an isosceles triangle. You can use either pencil and paper, or a draw program.
Label the angles. What are the measurements of the angles that are not equal to 90 degrees?
Describe the two sides opposite the angles that are not equal to 90 degrees.
Now draw an equilateral triangle. Label the measurements of the angles. Can an equilateral triangle ever be a right triangle too? Explain your answer.
Finally, draw a right triangle. Can this triangle ever have an obtuse angle? Explain your answer.

Best ResponseYou've already chosen the best response.0what are the properties of an isosceles triangle? all angles in a triangle add up to 180

Best ResponseYou've already chosen the best response.0so they are both 90 @triciaal

Best ResponseYou've already chosen the best response.1isosceles means two sides are equal right?

Best ResponseYou've already chosen the best response.1so lets see if we can draw a right triangle with both legs that look about equal

Best ResponseYou've already chosen the best response.1ok now it is clear that if the two legs are equal, the two angles are equal as well?

Best ResponseYou've already chosen the best response.1and it is also true that the total degrees in a triangle with be 180 you have already used up 90 in the right angle, which means both of those equal angles together must add up to 90 degrees

Best ResponseYou've already chosen the best response.1nice one again the sum of the measure of the angles is 180 and since all the sides are the same, all the angles are also the same so what is one third of 180?

Best ResponseYou've already chosen the best response.1so they are all equal 60 right

Best ResponseYou've already chosen the best response.1Can an equilateral triangle ever be a right triangle too? Explain your answer. NO since all the angles are 60, none are 90!!

Best ResponseYou've already chosen the best response.1Can an equilateral triangle ever be a right triangle too? Explain your answer. no, since "obtuse" means bigger than 90 you have already used up 90 in the right angle, so you only have 90 left for the other two angles

Best ResponseYou've already chosen the best response.1therefore each must be less than 90
