B'Little Petya learns how to write. The teacher gave pupils the task to write the letter A on the sheet of paper. It is required to check whether Petya really had written the letter A. You are given three segments on the plane. They form the letter A if the following conditions hold: The first line contains one integer t (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89t xe2 x80 x89 xe2 x89 xa4 xe2 x80 x8910000) -- the number of test cases to solve. Each case consists of three lines. Each of these three lines contains four space-separated integers -- coordinates of the endpoints of one of the segments. All coordinates do not exceed 108 by absolute value. All segments have positive length. Output one line for each test case. Print xc2 xabYES xc2 xbb (without quotes), if the segments form the letter A and xc2 xabNO xc2 xbb otherwise.'...
