The angle sum of all interior angles of a convex polygon of sides 7 is |
180° 540° 630° 900° |
900° |
$\text{Sum of interior angles} = (n - 2) \times 180^{\circ}$ Given that the number of sides ($n$) is 7: $\text{Sum of interior angles} = (7 - 2) \times 180^{\circ}$ $\text{Sum of interior angles} = 5 \times 180^{\circ} = 900^{\circ}$ |
