Answer 2

Answer:

A quadrilateral is a square if and only if it is both a rhombus and a rectangle (i.e., four equal sides and four equal angles). Oblong: a term sometimes used to denote a rectangle that has unequal adjacent sides (i.e., a rectangle that is not a square). Kite: two pairs of adjacent sides are of equal length.

Area: various methods; see below

Internal angle (degrees): 90° (for square and rectangle)

Edges and vertices: 4

In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.
