Proving a Quadrilateral is a Square

What is the first step in proving a quadrilateral is a square?

• Calculating the area

• Plotting the points on a graph

• Checking for parallel sides

• Finding the perimeter

Which formula is used to calculate the length of a side in a quadrilateral?

• Slope formula

• Distance formula

• Pythagorean theorem

• Area formula

What does it mean if all four sides of a quadrilateral are equal?

• It is a parallelogram

• It is a rhombus

• It is a rectangle

• It is a trapezoid

What must be proven in addition to equal side lengths to confirm a quadrilateral is a square?

• The area is maximum

• The diagonals are equal

• All angles are acute

• At least one pair of sides is perpendicular

How can you determine if two lines are perpendicular?

• Their slopes are equal

• Their slopes are opposite reciprocals

• Their slopes are undefined

• Their slopes are both zero

What is the slope of a line if it goes down 1 unit for every 1 unit it goes right?

• Undefined

• 1

• -1

• 0

What is the significance of finding a right angle in a rhombus?

• It confirms the rhombus is a trapezoid

• It confirms the rhombus is a square

• It confirms the rhombus is a rectangle

• It confirms the rhombus is a parallelogram
