Yes are congruent , SSS because the graph shows us two equal sides, if they are equal, then the upper and lower sides of the quadrilateral will be equal, for this reason we already have two equal sides, and since the triangles share the diagonal we can say that their three sides are equal
red and green sides are equal one by one,the red ones are the same because the drawing says so, and the green ones are the same because in a parallelogram the opposite sides have the same measure.
we already have that two of the three sides of each triangle are equal,and we can conclude that the third side is also the same, since the triangles share it
then the triangles are equivalent since their three sides are equal SSS
