Consider the earth as a sphere. Then one degree, in the East-West direction (longitude), at the equator would represent 1/360 of the equatorial circumference.
At the North or South pole, however, a one degree EW separation would amount to zero. Even a 180 degree separation would still be 0.
So, as you move further away from the equator, the longitudinal distances become smaller. At the equator a 7.5 minutes map would be a square (except that the earth is not a sphere but is slightly flattened). As you move North, the square becomes a trapezium, with the "vertical" sides tapering very slightly inwards as you move up the shape. When you reach the North Pole, the shape becomes a triangle. In between there are stages where the "verticals" have moved sufficiently towards one another so that the "square" becomes a rectangle.

Which geometric figure has more vertyices a rectangular pyramid or a triangular pyramid?
The rectangular pyramid - it has a square base, so has four vertices rather than the three of a triangular one.
How many rectangular faces does a rectangular prism have?
it has four rectangular sides and 2 square faces * * * * * It need not have ANY square faces. It can have six rectangular faces.
How many square faces have a rectangular prism?
It has 4 rectangular faces and 2 square faces (:
What is the difference between the shape of the side view of a rectangular pyramid and a top-down view of a rectangular pyramid?
Unlike a tetrahedron (a four-faced shape with all triangular faces), a pyramid has a square (or rhomboid) base and triangular sides. Thus, a view from any side will yield a triangular appearance, while a view from below or above shows a square or rectangular shape.
How many faces in a rectangular square pyramid?
A rectangular pyramid, or a square pyramid, has 5 faces in all.
