Since the options seem incorrect, kindly report an error for this question. Hopefully this gets reviewed.

Ans 2:

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 3:

Class : Class 8
A rectangle is a type of trapezium only and anyway the diagonals of a square is also equal

Ans 4:

Class : Class 9
wrong answer.it should be d

Ans 5:

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

Ans 6:

Class : Class 9

Ans 7:

Class : Class 10
rectangle is also a trapezium because atleast one pair of sides parallel……..

Ans 8:

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.

Wrong question guys !

Ans 10:

Class : Class 8

Ans 11:

Class : Class 9
all answers are correct, this question is wrong

Ans 12:

Class : Class 10
The answer is D

Ans 13:

Class : Class 8
This question is unclear if synopsis does not define it

Ans 14:

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 15:

Class : Class 9

Ans 16:

Class : Class 7
Answer should be D diagonals are equal in square as well So if diagonals are equal it need not be a rectangle

Ans 17:

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 18:

Class : Class 9

Ans 19:

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 20:

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 21:

Class : Class 8
D is answer

Ans 22:

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.

Ans 26:

Class : Class 8
i agree, A is correct, there is no incorrect answer, as a rectangle is a special trapezium
