## Is it possible to have a quadrilateral whose Each interior angle measure 90 degree?

Rectangles. A rectangle is one kind of quadrilateral with four right angles. This means each angle in a rectangle measures 90 degrees. Another property of a rectangle is that opposite sides are parallel to each other and equal in length.

**Can all the angles of a quadrilateral be 90 degree?**

Yes, all the angles of a quadrilateral can be right angles. In this case, the quadrilateral becomes rectangle or square.

### What is the opposite angle of 90?

hypotenuse

The hypotenuse is the side of a right triangle that’s opposite the 90-degree angle. It’s a term specific to math, specifically geometry. Hypotenuse comes from the Greek word hypoteinousa which means “stretching under.” The hypotenuse “stretches under” the right angle of a triangle, which has an angle of 90 degrees.

**How many maximum number of 90 degree angle are possible in a quadrilateral?**

3 obtuse angles

As we know, an obtuse angle is an angle between 90 degrees to 180 degrees. The sum of the interior angles of a quadrilateral is equal to 360o. So all the angles can’t be obtuse since then the sum will more than 3600. Therefore a maximum of 3 obtuse angles that a quadrilateral have.

#### Does a right angle have to be 90 degrees?

Is a Right Angle Only 90 Degrees? Yes, a right angle is always equal to 90°. It can never be other than this angle and can be represented as π/2 in radians. Any angle less than 90° is an acute angle and greater than 90° can be obtuse, straight, or a complete angle.

**Does a rectangle have 90 degree angles?**

Since a rectangle has four angles of equal measure, the measure of each must be 360/4, or 90 degrees.

## How many pairs of adjacent angles does a quadrilateral have?

four pairs

Thus there are four pairs of adjacent angles. (4) Similarly, in a quadrilateral if two angles don’t have any side in common, they are opposite angles.

**Can all the angles of a quadrilateral?**

No, all the angles of a quadrilateral cannot be acute angles. As, sum of the angles of a quadrilateral is 360°.

### How do you know if an angle is 90 degrees?

If the angle is indicated with a small square rather than a curved line, then the angle is meant to be 90 degrees. If the angle is a part of a shape such as a rectangle or square, then the angle is 90 degrees. If the angle is part of a triangle, add the measures of the other two angles.

**How many 90 degree angles are in a triangle?**

one

The triangle can have one 90 degree angle and two acute angles (angles less than 90 degrees). The sum of all the angles of a triangle is equal to 180 degrees. Therefore only one angle can be 90 degrees. The triangle having a 90-degree angle is also known as a right-angled triangle.

#### Which hybridization has more 90 angle?

Maximum number of angles equal to 90∘ will be seen in sp3d2 hybridization.
