## obliqueSomething that is oblique is slanted or not perpendicular. Oblique
coordinates are measured on a plane coordinate system whose axes
are not perpendicular. An oblique angle is any angle except
a right angle and an oblique triangle is any triangle that doesn't contain a right angle (i.e., one in which one
of the interior angles is obtuse). The first reference to "oblique angled
triangles" may have been by Thomas Blundevil in his Exercises in
1594. ## Related category• GEOMETRY | |||||
