Sorting Polygons: Strategies for Classification

This tutorial explains the importance of sorting polygons and introduces five criteria for sorting: number of sides, side lengths, parallel sides, types of angles, and lines of symmetry. Examples of sorting an isosceles triangle, a rectangle, and a rhombus are provided to illustrate the application of these criteria.

Why is it important to learn how to sort polygons?

• To distinguish between different shapes

• To improve drawing skills

• To enhance digital graphic design

• To solve algebraic equations

• No

• Yes, one pair

• Yes, two pairs

How many lines of symmetry does an isosceles triangle have?

• Three

• One

• Two

• None

What types of angles are found inside a rectangle?

• Only acute angles

• Only obtuse angles

• Only right angles

• A mix of acute and obtuse angles

How many lines of symmetry does a rectangle have?

What is a characteristic feature of the sides of a rhombus?

• Only one pair of sides is equal

• No sides are equal

• All sides are of different lengths

• All sides are equal

How many pairs of parallel sides does a rhombus have?

• None

• One

• Two

• Three

What types of angles does a rhombus typically have?

• Only obtuse angles
