Answer:
Equilateral
Step-by-step explanation:
I can see why this question my be difficult as you are given no angle or side measurements, but have no fear, you do have the answers right in front of you.
See the arcs and the lines? The arcs show you that the angles are all congruent (the same). The tick marks on the line segments function the same way, only they show you that the sides are congruent. It's also important to know what the definition of those triangles are.
Equilateral: All 3 sides are equal
Isosceles: No more than 2 sides are equal
Scalene: None of the sides are equal
If you know all this information, then you can figure out the answer, which is equilateral.
Good luck!
