Example 1
easyHow many sides and corners does a rectangle have?
Solution
- 1 Step 1: A rectangle is a closed 2D figure. Count its sides by tracing around it: top, right, bottom, left — that is 4 sides.
- 2 Step 2: Each place where two sides meet is a corner. A rectangle has 4 corners.
- 3 Step 3: Because all corners are right angles (90°), a rectangle is a special type of quadrilateral.
Answer
A rectangle has 4 sides and 4 corners.
Every corner of a rectangle is a right angle. Rectangles belong to the family of quadrilaterals — shapes with exactly four sides.
