question 12 (1 point)
which of the following properties are true of a parallelogram?
a parallelogram has:

• 4 right angles
• 1 pair of parallel sides
• 2 pairs of congruent sides
• 4 congruent sides
• no parallel sides
• 2 right angles
• no right angles
• 2 pairs of parallel sides

Explanation:

Define a parallelogram

A parallelogram is a quadrilateral with two pairs of parallel sides.

Analyze side properties

By definition, a parallelogram has 2 pairs of parallel sides. Additionally, opposite sides of a parallelogram are congruent, which means it has 2 pairs of congruent sides.

Analyze angle properties

A parallelogram does not necessarily have right angles (though rectangles, which are a subset of parallelograms, do). Thus, properties requiring right angles are not true for all parallelograms.

Answer:

• 4 right angles
• 1 pair of parallel sides
• 2 pairs of congruent sides (Correct answer)
• 4 congruent sides
• no parallel sides
• 2 right angles
• no right angles
• 2 pairs of parallel sides (Correct answer)
