Question

If we have ∠ABC as θ, reflex ∠ABC is equal to ________________.

• A. 180${}^{\circ }$ - θ
• B. -180${}^{\circ }$ + θ ​
• C. 360${}^{\circ }$ - θ
• D. 360${}^{\circ }$ + θ

Answer 1

The correct option is C

360${}^{\circ }$ - θ

From the figure, we can see that ∠ABC + Reflex ∠ABC = 360${}^{\circ }$

So, Reflex ∠ABC = 360${}^{\circ }$ - θ
