What types of angles are there in a rectangle?
right angles
How many right angle in a rectangle?
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.
What angle is a 2d rectangle?
A rectangle has 4 interior angles each being right angles
How can you prove that a rectangle is really a rectangle?
In a rectangle, all the opposite sides, and angles are congruent to each other. All 4 angles of the rectangle, are right angles.
Do some rectangles have no right angle?
No, all four angles with in a rectangle are right angles.
A rectangle is a parallelogram with a right interior angle?
Yes, that is what is rectangle is. One can prove that all of the angles are right angles.
Is a rectangle a parallelogarm?
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.)
Describe the methods to prove that a quadrilateral is a rectangle?
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.
What types of angles are there in a rectangle?

What angle is a 2d rectangle?
A rectangle has 4 interior angles each being right angles
Is a rectangle a parallelogram with a right interior angle?
Yes. If it has ONE right angle, then ALL four angles are right angles.
What Are the angles on a rectangle right acute or obtuse?
