Q. Interior Angle Sum: Concave Polygons?\newlineWhat is the sum of the interior angles of a PENTAGON?\newlineUse a protractor to measure the five interior angles in concave pentagon. Calculate the su
  1. Calculate sum of interior angles: Calculate the sum of the interior angles of a polygon using the formula (n−2)×180∘(n-2) \times 180^\circ, where nn is the number of sides.\newlineCalculation: (5−2)×180∘=3×180∘=540∘(5-2) \times 180^\circ = 3 \times 180^\circ = 540^\circ
