The term parallelogram refers to a four sided geometrical figure (in other words, a quadrilateral) in which there are two sets of parallel sides. The angles can vary; they can be right angles, or they can be acute or obtuse angles, as long as there are two sets of parallel sides. Angles are not said to be vertical to each other. Angles can be perpendicular to each other, but not vertical or horizontal. If angles are perpendicular, then they are right angles, in other words, 90o angles. Lines can be vertical, but angles can't.
The grammatical term for two or more words next to each other that begin with the same letter is alliteration.
Two lines that intersect and form 90-degree angles (right angles) are "perpendicular" to each other. You would call them "perpendicular lines."
2 lines passing through each other making exactly four 90 degree angles

Its all sides r equal. What differentiates a square from other shapes is that it has four sides of equal lengths and four identical interior angles of 90 degrees each. It is unique. The term for all sides being of equal length is equalateral. And the term for all angles being of equal measurement is equalangular.
It appears to be consecutive prime numbers
Decagon is a geometry term that refers to a polygon that has 10 sides and 10 angles. The angles of a decagon measure 144 degrees.
