Because the axle that the Earth rotate around isn't exactly perpendicular to the sun. This tilt gives us seasons and changing day lengths.
10 - 21 foot lenghts are the most common lenghts
the revolution of the earth along with the tilt in the earths axis causes: varying lenghts of day and night changing seasons if the earths axis were straightvand not tilted there would be no seasons,since every point on the earth would recieve the same amount of light each day of the year.nor would there have been any variation in the lenghts of day and night-they would lost 12 hours each.

If two polygons are similar then the ratio of their perimeter is equal to the ratios of their corresponding sides lenghts?
Most likely, no. The transmissions are different lenghts, and the truck body styles are different.Most likely, no. The transmissions are different lenghts, and the truck body styles are different.
Blue wave lenghts ( methane gas )
perimeter
centimeters or millimeters :)
Congruent means they have the same angles and side lenghts. All squares have the same angles (all at 90*) but not all the same side lenghts; a square can be 5x5x5x5 and another can be 6x6x6x6.
quadrilateral
no
