6-5 Conditions for Special Parallelograms - GEOMETRY

The video tutorial discusses the conditions that define special parallelograms, including rectangles, rhombuses, and squares. It explains how a parallelogram can be identified as a rectangle if it has one right angle or congruent diagonals. For rhombuses, the conditions include having consecutive congruent sides or perpendicular diagonals. The tutorial concludes by explaining that a square meets the conditions for both rectangles and rhombuses.

What condition must a parallelogram meet to be classified as a rectangle?

• It must have all sides equal.

• It must have one right angle.

• Its diagonals must be perpendicular.

• It must have no right angles.

Which of the following is NOT a condition for a parallelogram to be a rectangle?

• It has opposite sides parallel.

• Its diagonals are perpendicular.

• Its diagonals are congruent.

• It has one right angle.

Which of the following is a condition for a parallelogram to be a rhombus?

• Its opposite angles are equal.

• It has consecutive congruent sides.

• Its diagonals are congruent.

• It has one right angle.

If a parallelogram has diagonals that bisect its angles, what type of special parallelogram is it?

• Trapezoid

• Square

• Rhombus

• Rectangle

What is true about a square in terms of its classification as a special parallelogram?

• It is only a rectangle.

• It is only a rhombus.

• It is both a rectangle and a rhombus.

• It is neither a rectangle nor a rhombus.
