Best ResponseYou've already chosen the best response.1try calculating the length of the 3 sides if they are equal, it would be equilateral if not, you have to check if they apply Pythagoras theorem

Best ResponseYou've already chosen the best response.2If you want to prove it, find the lengths if each side and show pythagoras works or find the slope of the two lines that form the right angle and see if the slopes are negative reciprocals

Best ResponseYou've already chosen the best response.23/2 and ⅔ it's easier to see if you multiply one by 1 and then flip it, you get the other *negative reciprocals*
