What is a parallelagram with four right angles?
There are square's, rhombus', and rectangles. * * * * * Leaving aside the random apostrophes, the answer is incorrect. A rhombus cannot have a right angle (without becoming a square). The correct answer is "a rectangle, with a square as a special case."
What has 4 right angles and 2 pairs of parallel lines?
A shape that has 4 right angles and 2 pairs of parallel lines is a rectangle. In a rectangle, all four angles are right angles, meaning they measure 90 degrees each. Additionally, opposite sides of a rectangle are parallel, resulting in two pairs of parallel lines within the shape.
When is a square not a rectangle?
A square has 4 equal sides, and 4 equal angles and are considered paralellagrams A rectangle has 4 equal angles but not necessarily 4 equal sides, it is also a parallelagram.. On a square all sides are congruent, while in a rectangle only opposite sides are. So when is a square not a rectangle? what defines a rectangle and a square, each shape has to have 4 right angles. the sides are parallel and that in a square all four sides are congruent while in a rectangle only the opposite sides are congruent. So a rectangle must have opposite sides that are parallel and equal and four right angles. A square must have opposite sides parallel, all sides congruent, and four right angles. a rectangle is a parallelogram with four right angles, while a square is a parallelogram with four congruent sides and four right angles. By this definition a rectangle is a square since it has opposite sides that are congruent and parallel and it has four right angles. The question is, why a rectangle is not a square? A rectangle is not a square because it is not required to have four congruent sides.
Are some rhombuses rectangles?
Yes. The reason why is because a rectangle is a quadrilateral with four right angles and a rhombus can have four right angles and it is also a quadrilateral.
How many right angles are there in square?
There are four (4) right angles in a square.
