 1   I,  5 | another infinite line at right angles to it, E, and a moving radius,
 2   I,  12|       triangle should have its angles equal to two right angles,
 3   I,  12|      angles equal to two right angles, and on another the diagonal
 4  II,  4 |     being the sum of two right angles, to the number two. But
 5  II,  14|        but so as to make equal angles, and thus to a single centre,
 6  II,  14|       bodies always make equal angles, and are not parallel. This
 7 III,  8 |       other has the most acute angles, and the angles, they say,
 8 III,  8 |     most acute angles, and the angles, they say, produce warmth
 9 III,  8 |    Again, if the possession of angles makes a body produce heat
10 III,  8 |  another. For they all possess angles, the octahedron and dodecahedron
11 III,  8 |         since they too possess angles and contain atomic spheres
12  IV,  4 |       heavy things makes equal angles on every side with the earth’
