Most of what you are seeing is because it's pixelated. Pixels are square, therefore where they meet will be a right angle. Look for the scale,
count the pixels per "artifact", to see how much area is being covered with only one value. It makes a big difference sometimes.
AND.....I have taken the train from Chicago to California and back. This goes through much mountainous terrain, both alpine and desert. Rocks all
along the way do sometimes break in straight lines and right angles. I'm sure it depends on the crystalline structure of the rock. Think about salt
for an example. All the little cubes that come out of your shaker at the dinner table were broken from larger pieces, that were also cubic. Nothing
was cut, molded, cast, carved.......they just happen to break into little cubes.
Since crystalline structure is an image of the basic molecular form, and molecules are presumed to be the same universally, it follows that Mars
probably has rocks that break along straight planes, with right angles.
