Which term describes a circular chart divided into triangular areas proportional to the percentages of the whole?

• A. Pie chart
• B. Bar graph
• C. Line graph
• D. Tips

Answer: (A)

A pie chart is a circular chart cut into slices, with each slice’s size proportional to that part of the whole. In this type of chart, the angle and area of every slice reflect its percentage, so a portion worth 30% would take up about 108 degrees of the circle. This makes it easy to compare parts at a glance and see how each piece contributes to the total. A bar graph uses separate bars to compare values, not a circle of slices; a line graph shows changes over time by connecting points; and a term like “Tips” isn’t a chart type at all.
