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
