Quadrilaterals. Quadrilateral just means "four sides". (quad means four, lateral means side). A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
What is a polygon? (Definition) Polygons are geometric figures of the 2D plane made up of a series of closed segments. The number of segments (called sides or edges) is equal to the number of vertices (or corners) used to define the geometric shape of the polygon. What is a polyhedron? (Definition)
Shape B : One pair of equal angles (right angles), one pair of parallel sides. Shape C : 4 equal angles (right angles), 4 equal sides, 2 pairs of parallel sides. Shape D : 4 equal angles (right angles), each pair of opposite sides are equal in length, 2 pairs of parallel sides.
8 Ιουν 2024 · A quadrilateral is a flat geometric shape having four straight sides and four vertices. It is a type of polygon. The word ‘quadrilateral’ is derived from the Latin words ‘quadri’, meaning ‘four’, and ‘latus’, meaning ‘side’.
Quadrilaterals can be classified by whether or not their sides, angles, diagonals, or vertices have special properties. The classification schemes taught in elementary school involve the number of pairs of parallel sides, and the congruence of sides, and whether or not all the angles are right angles (all angles are congruent).
18 Ιουλ 2023 · A quadrilateral is a polygon with 4 edges, corners, and interior angles. The main shapes are square, rectangle, rhombus, kite, parallelogram, and trapezoid. In geometry, a quadrilateral is a two-dimensional closed shape or polygon that has four straight sides, four corners or vertices, and four interior angles.
A quadrilateral is a closed shape that is formed by joining four points among which any three points are non-collinear. In simple words, a quadrilateral is a polygon with 4 sides, 4 angles, and 4 vertices.
