Do we have any information about how the linesintersect?
See solution.
Practice makes perfect
If AC intersects BD at a right angle, the two segments are perpendicular to each other. However, to be able to claim this, we need some indication in the diagram that this is the case. We cannot just look at it and say that they appear to be perpendicular.
Since we do not have this information, we cannot say that the segments are perpendicular.
