True, the peak is the crest and the lowest is the trough.
The crest.
I'm guessing you're talking about Transverse waves? eg. ~ Waves consist of two parts - a crest and a trough. The crest are the high points, and a trough is the low points. When a crest meets another crest, the wave is amplified, causing constructive interference (the crests add to each other). The same thing occurs when a trough meets a trough. However, when a crest meets a trough, the wave is diminished, causing destructive interference (the crest and trough cancel each other out).
1) Crest of one wave meets the crest of other wave OR Trough of one wave meets the trough of other wave.
Crest of a second wave. In other words, the two crests, first wave and second wave, add up together, which is constructive.

Destructive interference takes place. Constructive interference occurs when the trough of one wave passes through the crest of another wave
The amplitude of the wave
The amplitude of the wave
They cancel each other.
