try 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

so its a right ?

hoblos Group TitleBest ResponseYou've already chosen the best response.1
they are actually AB = √13 BC = √13 CA = √26 right ?
 4 months ago

hoblos Group TitleBest ResponseYou've already chosen the best response.1
so let's see if it's right is CA^2 = AB^2 + BC^2 ?

I would plot it. If the choice is either equilateral or right triangle, you can tell by eyeball

If 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

which r the two lines that form the right angle?

phi Group TitleBest ResponseYou've already chosen the best response.2
lines AB and BC

the slopes dont match 1.5 and 0.66666667

3/2 and ⅔ it's easier to see if you multiply one by 1 and then flip it, you get the other *negative reciprocals*

which means the lines are perpendicular (form a 90º angle) so you have proven its a right triangle.
