Full description

Trapezoiderは、台形に関する計算をすばやく、美しく、直感的に行うための計算アプリです。面積、角度、長さ、体積、図心など、台形でよく使う計算をひとつのアプリにまとめました。黒と金を基調にした見やすい画面で、入力した値に合わせて図形がリアルタイムに変化します。主な機能・面積計算上底、下底、高さ、面積のうち3つを入力すると、残り1つを自動計算します。・角度計算底角、上角、片側張出などを計算できます。台形の形を確認しながら、角度の関係を把握できます。・長さ計算上底、下底、高さから脚の長さや対角線を計算できます。・体積計算円錐台、台形断面の角柱、四角錐台の体積計算に対応しています。用途に合わせてモードを切り替えられます。・図心計算台形の図心位置を計算できます。建築、土木、設計、学習用途で便利です。・表示設定小数点以下の桁数、四捨五入、切り捨て、切り上げ、表示単位を設定できます。こんな方におすすめ・中学、高校、大学で図形や工学を学ぶ方・授業や教材作成で台形の計算を確認したい先生・DIY、外構、間取り、面積計算を行う方・建築、土木、測量、設計の現場で素早く数値を確認したい方 Trapezoiderは、単なる計算機ではありません。台形に特化することで、必要な入力、結果、図形の変化をひとつの画面で自然に確認できるように設計しています。台形の計算を、もっと速く。そして、もっと美しく。
