Find the sum of all interior angles of a hexagon.

hard 3 marks Class 5 · Mathematics · Shapes and Angles

Answer

720 degrees

The correct answer is 720 degrees — For a hexagon $n = 6$ , so $(6 - 2) \times 180 = 4 \times 180 = 720$ degrees.

Step-by-step solution

Use the formula for the sum of interior angles of a polygon: $(n - 2) \times 180$ degrees, where $n$ is the number of sides.
For a hexagon $n = 6$ , so $(6 - 2) \times 180 = 4 \times 180 = 720$ degrees.

Common mistake: Using the wrong formula like

180 \times (n - 1)
