Question

1. the sides of a ladder are parallel. since the rungs are perpendicular to one side of the ladder, what conclusion can be made?the sides are parallel to the rungs.the sides are perpendicular to each other.the rungs are perpendicular to the other side.the rungs are parallel to the sides.

Explanation:

When two parallel lines (the sides of the ladder) are cut by a transversal (the rung), if the transversal is perpendicular to one of the parallel lines, then by the property of parallel lines and transversals, it is also perpendicular to the other parallel line.

Answer:

The rungs are perpendicular to the other side.
