Questions & Step-by-Step Solutions

What is the sum of the interior angles of a pentagon?
  • Step 1: Identify the shape you are working with. In this case, it is a pentagon, which has 5 sides.
  • Step 2: Use the formula to find the sum of the interior angles of a polygon. The formula is (n - 2) * 180°, where n is the number of sides.
  • Step 3: Substitute the number of sides (n = 5) into the formula: (5 - 2) * 180°.
  • Step 4: Calculate (5 - 2), which equals 3.
  • Step 5: Multiply 3 by 180°: 3 * 180° = 540°.
  • Step 6: Conclude that the sum of the interior angles of a pentagon is 540°.
