Classifying Quadrilaterals: Properties and Relationships

What is the essential question of the lesson?

• How to solve quadratic equations?

• How can you classify and compare quadrilaterals?

• What are the properties of triangles?

• How to calculate the area of circles?

What real-world example is used to introduce quadrilaterals?

• A shopping mall layout

• A school playground

• A city map

• A baseball field seating chart

What property do parallel lines have?

• They form a circle

• They are equidistant and never meet

• They are always curved

• They intersect at right angles

Which quadrilateral has four right angles?

• Parallelogram

• Trapezoid

• Rectangle

• Rhombus

What makes a square a special parallelogram?

• It has four congruent sides and four right angles

• It has one pair of parallel sides

• It has no parallel sides

• It has only two right angles

What is a trapezoid?

• A quadrilateral with two pairs of parallel sides

• A quadrilateral with exactly one pair of parallel sides

• A quadrilateral with four congruent sides

• A quadrilateral with no parallel sides

How are trapezoids and parallelograms different?

• Parallelograms have no parallel sides

• Trapezoids have exactly one pair of parallel sides

• Parallelograms have exactly one pair of parallel sides

• Trapezoids have two sets of parallel sides

Is a rhombus always a parallelogram?

• Only in specific cases

• Sometimes

• No, never

• Yes, always

Can a parallelogram be sometimes a rectangle?

• Sometimes

• Yes, always

• Only if it has congruent sides

• No, never

Why does the square intersect with both rhombuses and rectangles in the Venn diagram?

• Because it has no right angles

• Because it has properties of both rhombuses and rectangles

• Because it is neither a rhombus nor a rectangle

• Because it has exactly one pair of parallel sides
