    c and d.....as 15 and 7 are the equal alternate angles.....so c and d will be parallel

    2 will be always congruent to 5, they are verticall opposite angles, so no lines are parallel

    length can never be negative, right?? here, A to B is 1, B to C is 1, and C to D is 1, and that adds up to????

    ok i dont think it is A so it is either B or C

    vertical angles are those opposite angles that form when two lines intersect.....when two angles sum up to 90 they are called complementary angles, and when they sum up to 180 they are called supplementary angles.....what do u think about this one?? how much do they sum up to?

    @tanvirms Complementary angles are two angles with a sum of 90º. Supplementary angles are two angles with a sum of 180º. Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X.

    A+B=90 so they are complementary

    If <A and <B are vertical angles, and <A = 38°, find the measure of <B. A. <B = 7° B. <B = 57° C. <B = 38° D. <B = 142°

    vertical angles are always equal :)
