This is an example of emphasis. Because they painted the walls white, and then to draw in the emphasis they painted the walls bright red. As well as the chairs, just to make a design.
This is random rhythm. Because there are two black chairs, but then theres a red chair right in the middle. Then theres two different lamps. So that's why this picture is random rhythm.
This is an example of regular rhythm. Because the ceiling has triangles that are repeated. Also the windows at the top which are also squares and are repeated. Another one is the chairs which are the on the bars, with the sit, so the example is the bars holding up the seat.
This is an example of radical. Because There are three bikes that are, blue, purple, and red. They take the attention away from the table, flooring, and everything else, and has it towards the bikes.
This picture is symmetrical, because the mirrors are the same shape, and they have the same plant on the same counter, the same four chairs and the same table. They even have the same lamp.
Symmetrical- Because they have the same two lights, the same blinds, and the same type of window. Parts of the design are identical.
