Question

The sum of the interior angles of a quadrilateral is:



540°

720°

360°

180°

Answer 1

Use the general rule of

\[\large (n - 2) \times 180^{\circ}\]

so for a quadrilateral (4 sides) we have

\[\large (4 - 2) \times 180^{\circ}\]
\[\large 2 \times 180^{\circ}\]
\[\large 360^{\circ}\]

Answer 2

the answer is 360
there is an equation that looks like this: (n-2)*180 and n stands for the number of angles
