Types of angles:
• Acute angle: ,type of angle smaller than 90°
,
• Right angle: ,90° angle
,
• Obtuse angle: ,type of angle that is larger than 90° but lesser than 180°.
,
• Straight line: ,180° angle
,
• Reflex angle: ,type of angle larger than 180°
,
• Full circle: ,360° angle
If we divide the pie into six equal pieces, we get:
Also, as we know, a full circle such as the pie has a 360° angle, thus:
Each piece has a 60° angle, then it is an acute angle.
Answer: Acute angle.
