Question

Determine the reflex angle(s) from the given figure.

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (D)

Reflex angles are more than ${180}^o$ but less than ${360}^o.$

Let's go through each options.

Option (a): The measure of angle is more than ${180}^o$ but less than ${360}^o.$
Hence, it is a reflex angle.

Option (b): The measure of angle is less than ${180}^o.$
$\therefore$ This is not a reflex angle.

Option (c): The measure of angle is more than ${360}^o+{180}^o.$
$\therefore$ This is also not a reflex angle.

Option (d): The measure of angle is more than ${180}^o$ but less than ${360}^o.$
$\therefore$ This is a reflex angle.
