Question 1
Art project: Which polygon has four sides and four angles?
- Pentagon
- Rectangle
- Triangle
- Circle
Explanation: This question tests the ISEE Lower Level skill of identifying polygons based on their properties. A polygon is defined as a flat shape with straight sides and angles, and the number of sides always equals the number of angles in any polygon. The question asks for a polygon with four sides and four angles, which describes any quadrilateral. The correct answer is B (Rectangle) because rectangles have exactly four sides and four angles. While squares also have four sides and four angles, rectangle is the more general term that includes all four-sided polygons with right angles. Teaching strategies include showing students that they can count either sides or angles to determine a polygon's type, as these numbers are always equal. Use visual aids to demonstrate that pentagons have 5 sides/angles and triangles have 3 sides/angles.
