Obtuse and Oblique

Dr. Math,

Are the terms "obtuse" and "oblique" interchangeable?

Thank you for your answer,
     Kevin

No!  An Obtuse angle is one that is greater than 90 degrees.
An oblique angle is one that is not 90 degrees.

Example:

100 degrees is both obtuse *and* oblique
 80 degress is *only* oblique
 90 degrees is neither.

I hope this clears it up..
