Does a rectangle have four equal sides and four right angles?
four equal angles
What has four sides opposite sides and angles are congruent and has four right angles?
both a rectangle and square.
Can a parallelogram be a rectangle rhombus and square?
No, because a rectangle has four sides, and four right angles. So does a square. But, a rhombus has four sides, two obtuse angles, and two acute angles. Even though a rhombus does qualify as a parallelogram, (four sides, four angles) is does not qualify as a rectangle or square because is doesn't have four right angles. All squares are rectangles, but not all rectangles are squares because a rectangle has four sides, and four right angles, but with a square, all the sides have to be the same length.
What shape has four equal angles and two pairs of matching sides?
Assuming there are no more sides/angles, then it is a rectangle.
When does a parallelogram become a rectangle?
A parallelogram is only a rectangle if it has 4 right angles. A square is a rectangle, but not vice versa because a square has all equal side lengths, four sides, AND four right angles. A rectangle has four right angles and 4 sides.
