Respuesta :

This is about understanding the meaning of a rectangle and parallelogram.

Option A is the correct definition.

We are given the 2 statements as;

1)  A rectangle is a parallelogram with 4 right angles

2) A rectangle is a parallelogram

  • Let us define a rectangle and parallelogram;

- A rectangle is defined as a quadrilateral with four right angles. This means all the angles are equal. It also has 4 sides with the length of opposite sides being parallel to each other.

- A parallelogram is defined as a quadrilateral that has two pairs of parallel sides with the opposite sides of such parallelogram having equal length and the opposite angles being equal.

  • Option A; This is correct because the reverse statement is that; A parallelogram is a rectangle with 4 right angles, This is possible because the only condition where a parallelogram is a rectangle is when it has 4 right angles.

  • Option B; This is wrong because a rectangle is not a parallelogram.

  • Option C; This is wrong because not all parallelograms are rectangles.

  • Option D; This is wrong because a rectangle must have 4 right angles
