Answer:SSS
Explanation:
As you can see above the two triangles share a side, so you would count that as being a side.
Think of it as a freebie!
The lines or "tick marks" on the triangle let you know that it is a side.
This question may be confusing for some because it’s to triangles put together. For this type of question all you have to do is look at one triangle.
As previously mentioned above we have a freebie so that counts as one line and we have two sets of tick marks.
To get your answer you add up your tick marks or the sides give and you get three.
So your answer would be SSS!
