## Introduction

An arrowhead quadrilateral is a geometric shape characterized by having two opposite angles greater than 180 degrees, resembling the shape of an arrowhead.

### Purpose of the Calculator:

The Arrowhead Quadrilateral Calculator is designed to assist users in performing calculations related to arrowhead quadrilaterals. It helps users determine various properties and measurements of arrowhead quadrilaterals, including lengths, angles, perimeter, and area, making geometric computations faster and more accurate.

### Characteristics and Properties

An arrowhead quadrilateral is a geometric shape with distinct characteristics and properties:

• It has four sides and four angles.
• Two opposite angles are greater than 180 degrees, resembling the shape of an arrowhead.
• The other two angles are acute (less than 90 degrees).
• The sum of all interior angles is 360 degrees.
• It may have different side lengths and angle measures.

There are several types of arrowhead quadrilaterals based on their specific configurations:

• Obtuse Arrowhead Quadrilateral: One angle is obtuse, and the other three are acute.
• Right Arrowhead Quadrilateral: One angle is a right angle (90 degrees), and the other three are acute.

## Features of the Calculator

### Overview of Input Parameters

• Longer side (a): Length of the longer side of the arrowhead quadrilateral.
• Shorter side (b): Length of the shorter side of the arrowhead quadrilateral.
• Angle α: Measure of one of the acute angles (in degrees).
• Angle β: Measure of another acute angle (in degrees).
• Angle γ: Measure of the obtuse angle (in degrees).

### Calculation Methodology

The calculator utilizes the input parameters to perform calculations based on the properties and formulas of arrowhead quadrilaterals. It employs trigonometric functions and geometric principles to determine the following:

• Length (l)
• Height (h)
• Inner length (m)
• Missing length (n)
• Perimeter (p)
• Area (A)

### Output Values

After the calculation process, the Arrowhead Quadrilateral Calculator presents users with the following output values:

• Inner length (m): The calculated inner length of the arrowhead quadrilateral.
• Missing length (n): The calculated missing length of the arrowhead quadrilateral.
