Geometry Tutor - Quadrilateral

Geometry Tutor - Quadrilateral A 2-dimensional four sided polygon is called as a Quadrilateral. Different types of Quadrilateral are Opposite sides are parallel and equal. Area = base x height Two pairs of adjacent sides are equal. AB = BC and AD = CD Diagonals intersect at right angles. Area = (AC x BD)2 Opposite sides are parallel and equal. Each angle in a rectangle is 90. Area = Length x width All the four sides are equal. Diagonals are perpendicular. Area = (PQ RS)2 A pair of sides is parallel. Area = (a+b)h2 Here a, b are length of parallel sides And h is the height. All the sides are equal. Diagonals bisect each other. Each angle in a square is equal to 90 Area = side 1) A parallelogram with all sides equal and angles as right angles is a (a) Rectangle (b) Square (c) Rhombus (d) Kite Answer: b 2) Select a regular quadrilateral from the following (a) Rectangle (b) Parallelogram (c) Square (d) Rhombus 3) Statement I: A square is also a rectangle. Statement II: A rectangle is also a square. (a) Both I II are true (b) I is true, II is false (c) I is false, II is true (d) Both I II are false Answer: b 4) Sum of interior angles in a quadrilateral is (a)180 (b) 360 (c) 90 (d) cant be determined
