Classify the angle formed by lines measuring 40°.
Answer (1)
To classify an angle that measures 4 0 ∘ , we need to understand the different types of angles based on their measurements.
Acute Angle: An angle that measures less than 9 0 ∘ .
Right Angle: An angle that measures exactly 9 0 ∘ .
Obtuse Angle: An angle that measures more than 9 0 ∘ , but less than 18 0 ∘ .
Straight Angle: An angle that measures exactly 18 0 ∘ .
Reflex Angle: An angle that measures more than 18 0 ∘ , but less than 36 0 ∘ .
Full Rotation: An angle that measures exactly 36 0 ∘ .
Given that the angle measures 4 0 ∘ , it falls into the category of an Acute Angle because 4 0 ∘ < 9 0 ∘ .
In summary, the angle formed by lines measuring 4 0 ∘ is classified as an acute angle.
