triangle with sss

Are these two triangles congruent? If so, explain why. Make sure to explain why something is congruent if not already given.

I can’t see the picture you’re referring to. But yes — if you can show three pairs of corresponding sides are congruent, then the two triangles are congruent by the SSS (side–side–side) congruence postulate. If you want a full justification, either paste the diagram or describe the triangles and the given equalities; otherwise use the template below.

Template proof (replace letters with the ones in your figure):

1. Name the triangles you want to prove congruent, e.g. ΔABC and ΔDEF.
2. List the three pairs of congruent sides (these must be corresponding): AB = DE, BC = EF, and AC = DF. If any of these equalities is not explicitly given in the problem, say how you deduced it (common reasons: the side is shared by both triangles, the segments are radii of the same circle, endpoints are midpoints, sides of a parallelogram are equal, etc.).
3. By the SSS postulate, if three pairs of corresponding sides of two triangles are congruent, the triangles are congruent. Therefore ΔABC ≅ ΔDEF.
4. Conclude any required corollaries: corresponding angles are congruent (∠A = ∠D, ∠B = ∠E, ∠C = ∠F), corresponding medians/altitudes/whatever match, etc.

If you upload or describe your specific diagram, I’ll identify the three side pairs and write the exact SSS congruence proof for those triangles.
