About 台形の完全計算アプリ:Trapezoider
Trapezoider is a calculation app designed for quick, beautiful, and intuitive calculations involving trapezoids.
It combines commonly used trapezoid calculations—area, angles, length, volume, centroid, etc.—into a single app. The user-friendly black and gold color scheme displays the shape in real-time based on the entered values.
Main Features
* Area Calculation: Enter three of the following: top base, bottom base, height, and area; the app automatically calculates the remaining one.
* Angle Calculation: Calculate base angles, top angles, and overhangs. Understand angle relationships while viewing the trapezoid's shape.
* Length Calculation: Calculate leg lengths and diagonals from the top base, bottom base, and height.
* Volume Calculation: Supports volume calculations for frustocones, trapezoidal prisms, and truncated square pyramids. Switch modes according to your needs.
* Centroid Calculation: Calculate the centroid of a trapezoid. Useful for architecture, civil engineering, design, and educational purposes.
* Display Settings
You can set the number of decimal places, rounding, truncation, rounding up, and display units.
Recommended for:
* Students studying geometry or engineering in middle school, high school, or university
* Teachers who want to verify trapezoid calculations for lessons or curriculum development
* Those doing DIY, landscaping, floor plans, or area calculations
* Those who want to quickly check numerical values in construction, civil engineering, surveying, or design fields
Trapezoider is more than just a calculator.
By specializing in trapezoids, it is designed to allow you to naturally check the necessary inputs, results, and changes in the shape on a single screen.
Calculate trapezoids faster.
And more beautifully.
