Answer 1

so, i'm not sure if you know what the options mean so I'll tell you what they mean. You should be able to figure it out from there :)
right triangle- has one angle that is 90 degrees

equilateral triangle- the key word here is EQUI--it sounds like equal, meaning all angles are the SAME measure.

acute triangle- this means that all the angles are LESS than 90 degrees

obtuse triangle- one of the angles is going to be GREATER than 90 degrees.

let me know if you still don't get it.
