Geometry problems with AI: solving on the diagram step by step
Pick a topic or send a photo of the problem with its diagram. At each step the board highlights the angle or segment being discussed and the property we apply.
Yellow marks what the current step is about.
∠AOC = 40°
The diagram has two intersecting lines and one known angle.
Walk me through a geometry problem step by step (grade 7, topic: adjacent and vertical angles). Problem: Lines AB and CD intersect at point O, ∠AOC = 40°. Find the other angles. At each step, name the angle or segment we are looking for and the property we apply. Lay it out as: Given, Find, Solution with reasons in brackets, Answer. Before the last step, ask whether I can finish it myself.
The diagram on the board is an example for the topic. Type in your own problem or photograph it and attach the photo in the chat. Free on the Starter plan.
Problems on ready-made diagrams: 6 types for grade 7
In problems with ready-made diagrams, almost the whole problem is in the drawing. Click a diagram – the topic opens on the board above and the solution goes step by step.
How to solve geometry problems: read the diagram first
Half of the solution is seeing what the drawing already marks. Ticks, arcs and symbols are data – they are not always spelled out in words.
- 1
Redraw the diagram in your notebook and label all the points. It is easier to name angles with three letters.
- 2
List everything that is marked: equal segments, equal angles, degrees, parallel lines.
- 3
Put a question mark on what has to be found or proved.
- 4
Recall the properties of the figures in the diagram: adjacent angles, vertical angles, base angles, the sum of angles.
- 5
Write every step with its reason in brackets – then the solution can be checked at a glance.
- One tick – segments with the same tick are equal
- Two ticks – another pair of equal segments
- Arc – an angle; identical arcs mean equal angles
- Small square – a right angle, 90°
- Arrows on lines – the lines are parallel
- A ray between sides with equal arcs – the angle bisector
How to write up geometry problems in grade 7
Teachers usually ask for the same layout. A reason in brackets after each step is what separates a solution from an answer.
Given: ΔABC, AB = BC, ∠B = 40°
Find: ∠A, ∠C
Solution:
1) ∠A = ∠C (base angles of an isosceles triangle)
2) ∠A + ∠B + ∠C = 180° (sum of angles of a triangle)
3) ∠A = ∠C = (180° − 40°) : 2 = 70°
Answer: ∠A = ∠C = 70°.
GivenEverything from the problem and the diagram, in letters and numbers.
FindExactly what is asked. In a proof problem – "Prove".
ReasonThe property, theorem or test – in brackets.

Frequently asked questions
How do I solve grade 7 geometry problems?
Start with the diagram: label the points, list the marked equalities and degrees, and write down what has to be found. Then recall the property of the figure and write each step with its reason. The AI goes through these steps with you and helps if you get stuck.
Can the AI solve a problem from a photo of the diagram?
Yes, the chat accepts photos on the free Starter plan too. Photograph the problem together with the diagram so that the letters and marks are visible – the AI will read the drawing and explain the solution step by step.
How do I solve problems on adjacent and vertical angles?
Adjacent angles add up to 180°, and vertical angles are equal. If one angle is known where two lines cross, the adjacent angle is 180° minus that angle, and the vertical angles repeat the values you found.
How should geometry problems be written up?
Given, Find (or Prove), Solution and Answer. In the solution, give a reason in brackets for each step: a property, a theorem or a test. See the layout in the section "How to write up geometry problems in grade 7".
Will the AI check my solution to a geometry problem?
Yes, use the "Check" mode. Paste your solution: the AI checks whether you read the diagram correctly, whether the properties fit and whether there are mistakes in the calculations, and suggests how to fix them.
Are there solutions to textbook problems by page number?
No. There is no database by page and exercise number. Rewrite the problem or photograph it together with the diagram – the AI will work through your exact problem.
