'die Ecke' and 'der Knick' can both describe a place where something does not continue straight. 'Die Ecke' is usually a point or area where two lines, surfaces, or streets meet. 'Der Knick' means a bent or folded spot in something that was previously straight, for example in paper, wire, or a hose. You can confuse the words because both show a sharp change in direction. 'Ecke' fits better for rooms, streets, and shapes. 'Knick' fits better for things that are bent or folded.
