Question

i tried to figure this out but somehow i cant. can i get help

Answer 1

Important things to know:

1. The sum of the angles in any triangle is equal to 180º
2. An isosceles triangle has two angles that are equal in measurement, while the third one is not

 

Use these two details to consider the possibilities. Draw them out if it helps. You can do this! :)
