Jul 18, 2023 · 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. The sum of the interior angles is 360 degrees. The word “quadrilateral” comes from the Latin words ...
Jan 11, 2023 · Quadrilateral definition. A quadrilateral is a plane figure made with four line segments closing in a space. Quadrilaterals can be convex or concave and simple or complex. The easiest, fastest way to learn about quadrilaterals is to build one yourself. Find four straight objects to use as line segments (four = quad; side = lateral).
Jun 8, 2024 · a) Simple Quadrilateral. It is a type of quadrilateral with no self-intersecting sides. It can be either convex or concave. Square, rectangle, and dart are some examples of simple quadrilateral. b) Complex Quadrilateral. Also known as a crossed quadrilateral, it is a type of quadrilateral having self-intersecting sides.
Solved Examples on Quadrilateral. Example 1. Find the missing angle in the given quadrilateral. Solution: We know that the sum of all the angles of a quadrilateral is 360°. Hence, we can write it as follows: x + 77° + 101° + 67 = 360°. x + 245° = 360°. x = 360° – 245°.
