What is the Rectangle Diagonal Angle Calculator & How does it work?
A rectangle is a quadrilateral with four right angles. The diagonal of a rectangle can be calculated using the Pythagorean theorem, where the diagonal (d) is the hypotenuse of a right triangle formed by the length (l) and width (w) of the rectangle.
d = sqrt{l^2 + w^2}
d = diagonal, l = length, w = width

The angle (ΞΈ) between the diagonal and one of the sides can be found using trigonometry. Specifically, the tangent of the angle is the ratio of the opposite side to the adjacent side.
tan(theta) = frac{w}{l}
ΞΈ = angle, w = width, l = length

Frequently Asked Questions
How do I calculate the diagonal of a rectangle?
Use the formula d = √(l² + w²), where l is the length and w is the width.
What is the angle between the diagonal and one side of the rectangle?
Use tan(ΞΈ) = opposite/adjacent, where opposite is the shorter side and adjacent is the longer side.
Can I use this calculator for a square?
Yes, since a square is a special type of rectangle with equal length and width.
How do I find the angle if I know the diagonal and one side?
Use ΞΈ = arctan(opposite/adjacent), where opposite is the shorter side and adjacent is the longer side.
What units should I use for length and width?
Use consistent units (e.g., all in meters or inches) to get accurate results.
Is this calculator only for rectangles?
Yes, it is specifically designed for rectangles with four right angles.
How do I calculate the area of a rectangle if I know the diagonal and one side?
First, find the other side using Pythagoras (aΒ² + bΒ² = cΒ²), then multiply both sides to get the area.
