The angles may or may not be congruent. We simply don't have enough information. The key bit of info we need is whether those lines that appear parallel actually are parallel.
IF the lines were parallel, then we could use the corresponding angles theorem to conclude angle 5 and angle 6 were congruent.
The bottom line seems a bit off and it could intersect the top line, if you were to extend it out. This assumes the drawing was done correctly and to scale.
A common way to mark parallel lines is to place arrows, or double arrows, on the inside portion of the line. The arrows are not placed at the endpoints. Such arrows are not marked on these lines, so it appears the lines aren't parallel and hence the angles mentioned are not congruent.
