Answer:
All rungs are perpendicular to a side of a ladder.
Step-by-step explanation:
The problem tells us that ALL the rungs of a ladder are parallel.
It also tells us that the top rung (which is a subset of all the rungs) is perpendicular to a side of the ladder.
But if this top rung is perpendicular to a side but we know that ALL rungs are parallel, then this top rung is also parallel to the other ones and therefore, all the other rungs are also perpendicular to a side of a ladder.

The haka is a traditional war cry, war dance, or challenge in Māori culture. It is a posture dance performed by a group, with vigorous movements and stamping of the feet with rhythmically shouted accompaniment.[a]
War haka were originally performed by warriors before a battle, proclaiming their strength and prowess in order to intimidate the opposition, but haka are also performed to welcome distinguished guests, or to acknowledge great achievements, occasions or funerals, and kapa haka (performing arts) groups are very common in schools.
