Understanding Parallelograms

The video tutorial covers the properties of parallelograms, including opposite sides being parallel and congruent, opposite angles being congruent, and diagonals bisecting each other. It then explores special types of parallelograms: rectangles, rhombuses, and squares, highlighting their unique properties such as equiangular and equilateral characteristics, congruent and perpendicular diagonals, and the relationship between squares and rectangles.

Which property is true for the opposite sides of a parallelogram?

• They are perpendicular.

• They are parallel.

• They form right angles.

• They are unequal.

What is the relationship between consecutive angles in a parallelogram?

• They are equal.

• They are supplementary.

• They are congruent.

• They are complementary.

What makes a rectangle a special type of parallelogram?

• It has all sides equal.

• It has all angles equal.

• Its diagonals are perpendicular.

• Its diagonals are congruent.

In a rhombus, what is unique about its diagonals?

• They are perpendicular.

• They are parallel.

• They are equal in length.

• They do not bisect each other.

How do the diagonals of a rhombus interact with its angles?

• They bisect the angles into unequal parts.

• They bisect the angles into congruent parts.

• They make the angles complementary.

• They do not affect the angles.

What is a defining feature of a square?

• Diagonals are not congruent.

• All angles are right angles.

• It has no parallel sides.

• All sides are unequal.

Which statement is true about the sides of a square?

• Only adjacent sides are equal.

• All sides are equal.

• Only opposite sides are equal.

• All sides are different lengths.

What is true about the diagonals of a square?

• They are not equal.

• They are parallel.

• They are perpendicular and congruent.

• They do not bisect each other.

Are all squares rectangles?

• No, because they are not parallelograms.

• Yes, because they have four right angles.

• No, because they have unequal sides.

• Yes, because they have unequal angles.

Which of the following is not a property of a square?

• All sides are congruent.

• Diagonals are perpendicular.

• Opposite angles are supplementary.

• Diagonals bisect each other.
