Japanese geometry terminology 半直線 点Aを端点 点Bを通る 線分 AからBまでの線分
💡 Result:
ご質問いただいた用語について、数学的な定義と表記方法は以下の通りです。 1. 半直線（はんちょくせん） 点Aを端点とし、点Bを通ってその方向へ限りなく伸びる真っ直ぐな線のことを「半直線AB」と呼びます [1][2][3]。 表記の際は、端点となる点を先に書き「半直線AB」のように表します [1][4]。端点が異なるため「半直線AB」と「半直線BA」は別個の図形となります [4]。 2. 線分（せんぶん） 2点Aと点Bを両端とする真っ直ぐな線のことを「線分AB」と呼びます [1][5][6]。 線分の場合、「線分AB」と「線分BA」は同じ図形を指します [1]。 数学においては、直線（両方向に限りなく伸びる）、半直線（一方にのみ限りなく伸びる）、線分（両端が限られている）として明確に区別されます [7][8][6]。

ご質問いただいた用語について、数学的な定義を解説します。 線分AB 点Aと点Bを両端とする、その間を結ぶまっすぐな線のことです[1][2][3]。両端が固定されており、有限の長さを持つ図形です[1][4][5]。線分は向きを持たないものとして扱われることが一般的であり、線分ABと線分BAは同一のものを指します（線分AB = 線分BA）[6][5]。 半直線AB 点Aを始点（端点）とし、点Bを通ってその方向に限りなく伸びるまっすぐな線のことです[1][2][3][7]。点Aを端点として一方にだけ無限に続く図形であり、始点と方向性を持つ図形として扱われます[6][4][5]。そのため、一般的に半直線ABと半直線BAは異なる図形を指します（Aを始点としてBへ向かう線と、Bを始点としてAへ向かう線は別物です）[8]。 まとめると、線分は2点を結ぶ有限の線、半直線は1点を始点として一方に無限に伸びる線と定義されます[4][5]。

Use Japanese-specific Verbose geometry phrasing.
When $Verbosity='Verbose', line-segment emits 線分 A から B まで instead of AからBまでの線分. Move 線分 after the endpoints and add の. The geometry-ray branch emits 半直線 A から B まで; まで can imply that B is the endpoint, although a 半直線 extends through B indefinitely. Use Aを始点としてBを通る半直線.

Japanese geometry terminology endpoint line segment 終点 端点 始点
💡 Result:
In Japanese geometry and mathematics, these terms are used to describe the boundaries and directional properties of lines and line segments [1][2][3]. 1. 端点 (たんてん, tanten): Means endpoint. It is the general term for a point at the end of a line, line segment, or ray [1][2]. In geometry, a line segment is defined as having two distinct endpoints (端点) [4][2]. 2. 始点 (してん, shiten): Means starting point or source. It is used primarily when a line segment or ray has a defined direction or orientation (such as a vector or a directed line segment) [2][5][3]. For a directed line segment AB, point A is the 始点 [5][6]. 3. 終点 (しゅうてん, shuuten): Means end point or target. It is the pair term to 始点, used when a line segment or vector has a defined direction [5][6]. For a directed line segment AB, point B is the 終点 [6][3]. In summary, 端点 is the generic term for any boundary point of a geometric line object [1][2]. When that object is given a specific direction (as in vectors, directed line segments, or graph edges), the points are specifically identified as 始点 (start) and 終点 (end) [2][5][3].

Use 終点 for the endpoint label.
This branch emits 点終了 for verbose ClearSpeak or non-leaf coordinates. Replace it with 終点, the established Japanese term paired with 始点.

Verbose said 半直線 A から B まで, which claims the ray stops at B. A ray has A as its endpoint and continues through B, so read it as A を始点として B を通る. A segment does end at its second point, so から...まで stays there; a test now pins the two apart.

Fifth of the small PRs from daisy#715, independent of the others.
The geometry terms were transliterated from English rather than translated. Japanese has settled words for all of these, taught in school, so the katakana forms are not a stylistic choice — 「レイ」 is not a word anyone would recognise as a ray.
In
geometry.yaml, the verbose "from A to B" forms also needed the particles rearranged: 「ラインセグメントから A に B」 does not parse as Japanese. They now read 「線分 A から B まで」 and 「半直線 A から B まで」.arcindefinitions.yamlis the geometric arc only. The アーク in アークタンジェント and friends is the standard reading of the inverse trigonometric functions and is untouched.Tests
geometry_termscovers line-segment, directed-line-segment, line, ray and arc through theintent='…($x,$y)'form theentests use, andgeometry_pointcovers the three-argument point.Note on the audit
This one does not move
audit-translations: rule differences stay at 0, including for the two rules that gained a 「まで」. Only match patterns and variable blocks appear to count there, so adding a closing word is free. (The structural question I raised in daisy#715 still stands for daisy#720 and daisy#721, where the match had to change.)Summary by CodeRabbit
