Answer 1

Question

• what is quadrilateral

Answer

• In Euclidean plane geometry, a quadrilateral is a polygon with four edges and four vertices. Other names for quadrilateral include quadrangle, tetragon, and 4-gon. A quadrilateral with vertices, and is sometimes denoted as
• 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°

Answer 2

Answer:

In Euclidean plane geometry, a quadrilateral is a polygon with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon, 5-sided polygon, and hexagon, 6-sided polygon), and 4-gon (in analogy to k-gons for arbitrary values of k). A quadrilateral with vertices {\displaystyle A}A, {\displaystyle B}B, {\displaystyle C}C and {\displaystyle D}D is sometimes denoted as {\displaystyle \square ABCD}{\displaystyle \square ABCD}.
