Answer:
In a parallelogram, consecutive angles are supplementary.
Step-by-step explanation:
Consecutive angles in a parallelogram have a sum of 180°; this means they are supplementary.
All angles in a parallelogram are not necessarily congruent; the second statement is therefore not true.
Consecutive angles in a parallelogram are not necessarily congruent; therefore the third statement is not true.
Consecutive angles in a parallelogram are not complementary, as they add up to 180° instead of 90°.
