Answer: AAS
Step-by-step explanation:
In the given picture , we have two triangles having two angles [tex](70^{\circ}\text{ and }30^{\circ})[/tex]and one non-included sides (10) congruent.
Then by AAS criteria of congruence , both the triangles are congruent.
- The AAS criteria of congruence [Angle-Angle-Side] tells that if two angles and a non-included side of a triangle are congruent to the corresponding two angles and a non-included side of other triangle then the triangles are congruent.
