 # Quick Answer: What Is The Interior Angle Of A Rectangle?

## What is the angle of a rectangle?

90°A rectangle is a four-sided flat shape where every angle is a right angle (90°).

Opposite sides are parallel and of equal length (so it is a Parallelogram)..

## What is the total angle of a rectangle?

360 degreesProof: This follows directly from the Quadrilateral Sum Conjecture which says that the sum of angles in any convex quadrilateral is equal to 360 degrees. Since a rectangle has four angles of equal measure, the measure of each must be 360/4, or 90 degrees.

## What is the formula for interior angles?

An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

## What is meant by interior angle?

noun Geometry. an angle formed between parallel lines by a third line that intersects them. an angle formed within a polygon by two adjacent sides.

## What is the interior angle of a hexagon?

120°Hexagon/Internal angle

## What do the internal angles of a rectangle add up to?

The angles of a rectangle add up to 360°.

## Are all angles equal in a rectangle?

The angles of a rectangle are all congruent (the same size and measure.) Remember that a 90 degree angle is called a “right angle.” So, a rectangle has four right angles. Opposite angles of a rectangle are congruent. Opposite sides of a rectangle are parallel.

## What is the interior angle of a decagon?

144°Decagon/Internal angle

## What is interior angle of a triangle?

60° (for equilateral)Triangle/Internal angle

## Does a rectangle have parallel lines?

A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.

## Can a rectangle have equal sides?

A rectangle has four sides, but these are not all equal in length. The sides parallel to each other are congruent. Thus, the long sides are of equal…

## How many interior angles are formed in a triangle?

three interior anglesAn interior angle is an angle inside the shape. From the above diagram, we can say that the triangle has three interior angles.
