Answer 1

A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices. Other names for quadrilateral include quadrangle and tetragon. A quadrilateral with vertices A, B, C and D is sometimes denoted as {\displaystyle \square ABCD}.

Step-by-step explanation:

Area: ½ x diagonal x (sum of perpendicular heights)

Perimeter: sum of sides of the quadrilateral

Number of vertices: 4

Number of edges: 4

Internal angle: 90° (for square and rectangle)

Sum of interior angles: 360°

Schläfli symbol: (for square)

Degrees

The total measure of all the four interior angles of a quadrilateral is always equal to 360 degrees. The sum of interior angles of a quadrilateral fits the formula of polygon i.e.
