to answer these you need to know congruent means identical size and shape (i.e. the triangles are exact matches)
If you know that the 3 sides of a triangle exactly match another triangle's 3 sides, then you know the triangles are congruent. People say if you have side-side-side, the triangles are congruent. They abbreviate that sss. For example, |dw:1443727270825:dw|
