Question

Classify the following triangle as acute obtuse or right 132 36 12

Answer 1

Hey!

Acute angles are angles that measure less than 90°. Obtuse angles are angles that measure more than 90° but less than 180°. Right angles are angles that measure exactly 90°.

132° is greater than 90°, but less than 180°. That means it's an obtuse angle.

36° is less than 90°. That means it's an acute angle.

12° is also less than 90°. That means it's also an acute angle.

$132\° = obtuse \\ 36 \° = acute \\ 12 \° = acute$

Since one of the angles is obtuse, it is an obtuse triangle.

Good luck and hope this helps! :)
