MCQ
The measurement of Complete angle is:
  • A
    $180^\circ$
  • B
    $0^\circ$
  • ✓
    $360^\circ$
  • D
    $90^\circ$
✓

Answer

Correct option: C.
$360^\circ$

$x + y = 180^\circ $ (Linear Pair)
$w + z = 180^\circ $ (Linear Pair)
On adding above equations
We get, $x + y + w + z = 180^\circ + 180^\circ = 360^\circ $
Sum of all the angles around a point is $360^\circ .$
