Classifying Quadrilaterals Using Coordinate Geometry

What is the primary goal when classifying quadrilaterals?

• To determine the most specific classification possible

• To identify if it has four sides

• To find the area

• To calculate the perimeter

What does a quadrilateral mean?

• A circle divided into four equal parts

• A polygon with four sides

• A shape with four angles

• A triangle with an extra side

What distinguishes a parallelogram from a trapezoid?

• Equal side lengths

• Four right angles

• Two pairs of parallel sides

• One pair of parallel sides

How do you determine if opposite sides are parallel in a quadrilateral?

• By checking if they have the same slope

• By measuring the angles

• By calculating the area

• By comparing their lengths

What classification is a quadrilateral if it has one pair of parallel sides?

• Parallelogram

• Trapezoid

• Rectangle

• Square

What additional feature does an isosceles trapezoid have?

• Two pairs of parallel sides

• Equal non-parallel sides

• Four right angles

• All sides equal

How is the length of a side in a quadrilateral calculated?

• Sum of all angles

• Square root of the sum of squared differences in coordinates

• Multiplying the slopes

• Adding the slopes

What does it indicate if all sides of a quadrilateral have the same length?

• It's a rectangle

• It's a trapezoid

• It's a parallelogram

• It's a square

Why is it important to show every calculation in geometry?

• To ensure accuracy and understanding

• To make the work longer

• To use more paper

• Because it's a requirement
