Personal AI Geometry Tutor Online That Teaches the Method
Photograph the diagram and the tutor asks what you can justify from what is marked on it, because geometry marks are attached to reasons rather than to conclusions and a correct answer with no justification scores very little.
What is the AskSia AI geometry tutor?
The AskSia AI geometry tutor is a personal tutoring tool that teaches proof and justification rather than answers. It asks what the diagram actually tells you, builds the chain of reasons with you when you ask, and puts a related configuration back to you. It covers angles and parallel lines, triangle congruence and similarity, quadrilaterals, circle theorems, area and volume, coordinate geometry and transformations. It answers in eight languages. Students on the AskSia A+ plan are covered by the Grade Confidence Guarantee. AskSia is a study aid, not an answer key.
如同真人導師的四個階段
解答出現時，解題工具就完成任務；當你能獨自解下一題，輔導才算完成。
給推進方向，而不是直接給解答
它指出卡住的步驟，再把問題交回給你走出下一步。
逐行說明，搭配圖解
需要更多協助時，它會逐行帶你走過解法，而不只告訴你最終結果。
它會反過來問你一題
在繼續之前，它會用一個簡短問題確認下一步是否真正屬於你。
稍後再回來複習
弱項會在更適合主動回憶、鞏固解題方法的時機再次出現。
考試還有三週
導師會刻意放慢節奏，為下一題留下可重複使用的解題方法。
每學期最容易失分的三個習慣
Geometry is the one school maths topic graded on justification. These three are where the marks go.
Stating a conclusion without a reason
Congruent by itself earns nothing, because the mark is attached to naming which criterion applies. The tutor asks which reason before it accepts the claim.
Assuming from the picture
Diagrams are rarely to scale and equal looking sides prove nothing. The tutor asks what is actually marked on the diagram.
Proving in the wrong order
A proof that uses a fact before establishing it is incomplete however true it is. The tutor asks what you can justify from the given information first.
不是題庫，而是從你的錯誤建立的測驗
Your marks are not lost evenly, so your practice is not spread evenly. Try this one.
這位導師涵蓋的內容
School and introductory geometry, weighted toward the reasoning that carries the marks.
Moving into trigonometry or coordinate work? Both build directly on this. Still shaky on the algebra used in coordinate geometry?
Four things a maths tutor does that a chat box does not
它了解你的學習歷程，不只是一個問題
下一次輔導會從你真正感到困難的步驟開始，而不是泛泛地重講整個主題。
它會畫出圖解，不只列出代數式
圖解會帶著標記與解題過程的每一步並列呈現，因為視覺化推理本身也能得到分數。
它會找出你自己解題過程中的第一行錯誤
拍下做錯的嘗試，它會找到解法最早偏離的步驟，接著講清這一步。
它依照你的課程方式檢驗理解
長答題需要依照你自己試卷的格式練習，而不是套用選擇題題庫。
Why the answer is the smallest part of the mark
Geometry questions award marks for the chain of reasons, not the conclusion, which is why a student who can see the answer instantly can still score two out of six. The tutor refuses to accept a claim without the reason attached.
Personal here means it remembers which reasons you cannot yet name. Seeing that two triangles are congruent and knowing which criterion to quote are separate skills, and only the second one is marked.
It tutors in English, German, Japanese, Korean, Spanish, Portuguese, Simplified Chinese and Traditional Chinese, and reads photographed diagrams.
學生真正會問的問題
Does it just give me the proof?
No. It asks what the diagram actually tells you and builds the chain of reasons with you. Each walkthrough ends with a related configuration put back to you.
Can it read a photographed diagram?
Yes, including your own annotations and crossings out, which is the fastest way to ask about a marked question.
Does it cover circle theorems?
Yes, and it teaches you to identify which theorem the diagram was constructed for, which is the step most students skip.
Does it help with coordinate geometry?
Yes, including completing the square to find a circle's centre and radius, which is where algebra and geometry meet most often.
Can it check a proof I wrote?
Yes. It marks the first step that uses something not yet established, which is the most common way a true proof still loses marks.
Is using an AI geometry tutor allowed?
AskSia is built as a study aid, not an answer key. Check your own institution's policy before using any tool on graded work.
