This page introduces an additional circle theorem rule that is crucial for solving more complex problems.
Definition: A perpendicular line from the center of a circle to a chord bisects the chord and forms right angles.
This theorem is particularly useful when dealing with problems involving chords and their relationships to the circle's center and circumference.
Highlight: Understanding this theorem can significantly simplify calculations in problems involving chord lengths and angles within circles.
This page presents a series of circle theorem questions and answers, demonstrating how to apply the rules in problem-solving scenarios.
Example: In question 2, the solution demonstrates how angles at the center are twice the size of angles at the circumference, a key principle in circle theorems explained with examples.
This page presents more challenging circle theorem questions, requiring the application of multiple rules and deeper analytical thinking.
Highlight: These problems demonstrate how complex circle theorem problems and solutions often require a step-by-step approach, combining multiple theorems to reach the final answer.
This page focuses on proving circle theorems and solving highly complex problems, ideal for advanced students and GCSE circle theorems preparation.
Example: The proof question demonstrates how to construct a formal geometric proof using circle theorem rules, an essential skill for advanced mathematics.
Highlight: These problems are excellent practice for students preparing for difficult circle theorem questions and answers in exams.

This page introduces eight essential circle theorem rules, providing a foundation for understanding geometric relationships within circles.
Definition: Circle theorems are geometric principles that describe relationships between angles, lines, and points in and around circles.
Highlight: These rules are often combined in complex geometric problems, requiring students to apply multiple theorems simultaneously.
Example: Rule 2 and Rule 3 are frequently seen together in diagrams, where a tangent forms a right angle with a radius, and two radii create an isosceles triangle within the circle.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
