Step-by-step explanation:
- <FGL is acute
- <HGF is acute
- <KGH is acute
- <KGF is obtuse
- <KGL is obtuse
- <HGL is right
value of complement is 90 and obtuse angle refers to angles that is above 90. complement can be said right angle but not obtuse.
- The sum of two acute angles sometimes results in an obtuse angle.
- Two obtuse angles are never supplementary.
- The sum of two right angles always results in a straight angle.
