Answer 2

Let us assume a triangle ABC which has only one acute angle (say ZA) Then we have acute angle below 90°

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). an obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

Acute Angle - An angle less than 90 degrees. ... Obtuse Angle - An angle more than 90 degrees and less than 180 degrees. Straight Angle - An angle that is exactly 180 degrees.
