Answer should be D diagonals are equal in square as well So if diagonals are equal it need not be a rectangle
Ans 5:
Class : Class 8
all options are true, i think option(c) should be "Triangle is a polygon whose exterior angle is double its interior angle". This way option(c) will be INCORRECT
Ans 7:
Class : Class 8
i agree, A is correct, there is no incorrect answer, as a rectangle is a special trapezium
Ans 9:
Class : Class 9
A is correct. By definition, a trapezium has ONLY ONE pair of parallel sides. A rectangle has 2 pairs of parallel sides, hence it is not a trapezium.

everyone to kindly check my panswer post it will most probably help u resolve what is the answer and please if there is any incorrect answer in my provided answer, please tell that thing.

Class : Class 8
all options are correct(A) a rectangle follows all the characteristics of a trapizium. It has one pair of parllel sides. it has four sides and sum of all the angles is 360(b) it can be drawn like one angle is 90 and four sides are 40,40,50,50 than it is a rectangle which is quadrilateral(c)It is a law that sum of ext. angles in every polygon is 360 and sum of int. angles in a triangle is 180 which is half of 360(d) all the quadrilaterals that have equal diagonals follow all the rules of a rectangle like square which has two set of equal and parllel sides and its diagonals are equal. A square also has all right angles.

A rectangle is a type of trapezium only and anyway the diagonals of a square is also equal

Class : Class 9
Wrong Question guys both a and d look incorrect as rectangle is not a trapezium and even square's diagonals are equal.
Ans 18:
Class : Class 9
Trapezium is a quadrilateral with two parallel sides. Parallelogram is a special case of trapezium and rectangle is a special case of parallelogram, hence rectangle is a special case of trapezium
Ans 23:
Class : Class 9
all options can be correct but if we see logically, option (D) states that "if the diagonals of a quadrilateral are equal it must be a rectangle" whereas the diagonals of a kite can also be equal.
Ans 25:
Class : Class 10
Both a and d options are correct, its marker wrong. Rectangle is a special trapezium and square also has all sides equal
Ans 26:
Class : Class 10
The answer is D as Rectangle is also a special type of trapezium so it is correct . Also, the option B is correct. Option C is correct too as interior angle sum of triangle is 180 and the exterior angle sum is double i.e. 360The correct answer would be option D as isosceles trapezium also has its diagonals equal therefore it is the incorrect statement required. Therefore, the answer should be D instead of C

But B has slanting line of symmetry.The line of symmetry doesn't means only to be strategy
Ans 3:
Class : Class 6
According to me the correct answer to this question is
D]
Because it has a line of symmetry from top to bottom
Ans 4:
Class : Class 5
the answer to this question can also be b because option b also has a line of symmetry
Ans 5:
Class : Class 5
D is the answer because it is straight but option B is not correct because over here it is slanting , and there is no such symmetry

It's simple addition and subtraction. The total cost of both toys is 52.45+25.32=77.77
You gave him a hundred rupee note. So you gave him 22.23 rupees morethe actual prize which you would recieve as change. So the answer is 22.23
(100-77.77=22.23)
