     12 An obliquangled triangle is either Obtuſangled or Acutangled.
     The diviſion of an obliquangled triangle is taken from the ſpeciall differences of an oblique angle. For at the 15 e iij, we were taught that an oblique angle was either obtuſe or acute: Therefore an obliquangled triangle is an obtuſeangle, and an Acutangle.
