The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is:
Slopes of opposite sides are equal<\/strong><\/p>\n\n\n\n

Therefore, ABCD is a parallelogram<\/strong> because both pairs of opposite sides are parallel.<\/strong><\/p>\n\n\n\n

Explanation<\/h3>\n\n\n\n

A parallelogram<\/strong> is a quadrilateral where both pairs of opposite sides are parallel<\/strong>. The most direct way to prove that a figure is a parallelogram is by using the slopes<\/strong> of its sides. In coordinate geometry, if two line segments have the same slope<\/strong>, they are parallel<\/strong>.<\/p>\n\n\n\n

In the context of this question:<\/p>\n\n\n\n

    \n
  • You are told that REMA 47:0<\/strong>, which is likely a reference to a coordinate system or problem number.<\/li>\n\n\n\n
  • You are given that BC || AD<\/strong> and CD || BA<\/strong>.<\/li>\n\n\n\n
  • These notations imply that side BC is parallel to side AD<\/strong>, and side CD is parallel to side BA<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    In coordinate geometry, this means:<\/p>\n\n\n\n

      \n
    • The slope of BC = slope of AD<\/strong><\/li>\n\n\n\n
    • The slope of CD = slope of BA<\/strong><\/li>\n<\/ul>\n\n\n\n

      Since both pairs of opposite sides<\/strong> have equal slopes, they are parallel<\/strong>, satisfying the definition of a parallelogram<\/strong>.<\/p>\n\n\n\n

      Let\u2019s break down why other options are incorrect:<\/p>\n\n\n\n

        \n
      • “Lengths of consecutive sides are not equal”<\/strong>: This may be true, but it’s irrelevant. A parallelogram does not require consecutive sides (like AB and BC) to be equal\u2014only opposite sides.<\/li>\n\n\n\n
      • “Slopes of consecutive sides are not equal”<\/strong>: This is also not a requirement. In fact, we expect slopes of consecutive sides (like AB and BC) to differ unless it’s a rectangle or square.<\/li>\n\n\n\n
      • “Lengths of opposite sides are equal”<\/strong>: While this is a property<\/em> of parallelograms, it is not a valid proof on its own<\/em> unless both pairs are shown to be equal. The slope (parallelism) is a stronger and more direct geometric proof.<\/li>\n<\/ul>\n\n\n\n

        Conclusion:<\/h3>\n\n\n\n

        Since both pairs of opposite sides have equal slopes<\/strong>, they are parallel<\/strong>. Therefore, ABCD is a parallelogram<\/strong> because both pairs of opposite sides are parallel<\/strong>.<\/p>\n\n\n\n
