I would say B.The measures of corresponding angles of ABCD and KLMN are in the ratio 1 : 2, but the lengths of corresponding sides of ABCD and KLMN are not proportional.

Answer:

Option A  is right

Step-by-step explanation:

For any two geometrical figures to be similar we must have either the sides are in proportion or all angles are congruent.

If angles are not congruent then the two polygons cannot be similar. So option B which says angles are in the ratio 1:2 is incorrect.

If sides are equal, the two polygons need not be similar, example, a square and a rhombus.  Hence option C is wrong

If sides are proportional and angles are not congruent then similarity cannot be there. Hence incorrect option d

Only correct answer is

Option a) The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.
