True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
It is always true because two congruent angles that are complementary both measure 45 degrees.
false
True. Vertical angles are formed by the intersection of two lines and are always equal in measure, while complementary angles are two angles whose measures add up to 90 degrees. Since vertical angles can be any angle measure and are equal, they cannot be complementary unless both angles happen to be 45 degrees, which is not the case in general.
False because complementary angles have a sum of 90 degrees.
yes
true
Sometimes
Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.

Select one: a. False; the angles may be supplementary. b. True c. False; one angle may be in the interior of the other. d. False; the angles may be adjacent.
True.
A linear pair are always supplementary, 180 degrees not 90.
True. When two lines intersect, they form vertical angles, and the chords created by these intersecting lines can be considered supplementary if the angles formed by the chords at the intersection add up to 180 degrees. Thus, intersecting chords can indeed correspond to supplementary vertical angles.
