Question

Each list shows the interior angle measures of a quadrilateral. Which set of measures describes a quadrilateral that cannot be inscribed in a circle?

69°, 103°, 111°, 77°

52°, 64°, 128°, 116°

42°, 64°, 118°, 136°

100°, 72°, 80°, 108°

Answer 1

what is ur guesss?

Answer 2

A?

Answer 3

Is it not A?

Answer 4

Why is it A though? I wanna see what your thought process is.

Answer 5

dont really have a way to type it out but I picked C last time and it was wrong, So im guessing its A. Im timed on this test and I have 5 min left so I want to get the right answer

Answer 6

You aren't supposed to post questions from a test, didn't you see yesterdays post about that?

Answer 7

Whatever

Answer 8

Is the answer A?

Answer 9

^ i would say A

Answer 10

thank you

Answer 11

The theorem at work for solving this problem is the following:

If a quadrilateral is inscribed in a circle, then opposite angles of the quadrilateral are supplementary. The task is to find two pairs of supplementary angles among the options and NOT to choose that option.

Which set of measures describes a quadrilateral that **cannot** be inscribed in a circle?
