From Wikipedia: "...a rectangle is any quadrilateral with four right angles". So there isn't much to prove, that's how the rectangle is defined.
right angles
4 right angles. A right angle is a 90 Degree measure like for example: L <---- 90 degree measure. And the rectangle has 4 angles like that so it means it has 4 right angles.
A rectangle has 4 interior angles each being right angles
In a rectangle, all the opposite sides, and angles are congruent to each other. All 4 angles of the rectangle, are right angles.
No, all four angles with in a rectangle are right angles.
Yes, that is what is rectangle is. One can prove that all of the angles are right angles.
Yes, a rectangle is a special kind of parallelogram - one that has a right angle. (You can prove that if it has one right angle all angles are right.)
you can prove any one of these statements to prove that quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.
right angles
No. By definition, all the angles of a rectangle are right angles.
There are no acute angles in a rectangle which has 4 equal interior right angles
Not normally but in the shape of a rectangle it has 4 right angles.
4 right angles. A right angle is a 90 Degree measure like for example: L <---- 90 degree measure. And the rectangle has 4 angles like that so it means it has 4 right angles.
No, a rectangle cannot have an obtuse angle. By definition, a rectangle is a quadrilateral with four right angles (90-degree angles). An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. Therefore, in a rectangle, all angles must be right angles, making it impossible for an obtuse angle to exist within a rectangle.
A rectangle has 4 interior angles each being right angles
Yes. If it has ONE right angle, then ALL four angles are right angles.
In a rectangle, all the opposite sides, and angles are congruent to each other. All 4 angles of the rectangle, are right angles.
