Fun with Inscribed Angles: Worksheets and Easy Examples!

Inscribed Angles and Circle Theorems - A comprehensive guide to understanding the relationships between inscribed angles, arcs, and circle theorems.

• The inscribed angle of a circle formula states that an inscribed angle measures half of its intercepted arc
• Three key corollaries explain relationships between inscribed angles, semicircles, and quadrilaterals
• The tangent chord theorem establishes that the angle between a tangent and chord equals half the intercepted arc
• Practical examples demonstrate how to solve problems using these geometric principles

Page 1: Understanding Inscribed Angles and Circle Theorems

This page introduces fundamental concepts about inscribed angles that intercept the diameter of the circle and related theorems. The content begins with essential definitions and progresses through key theorems and practical examples.

Definition: An inscribed angle is an angle whose vertex lies on a circle and whose sides are chords of the circle.

Highlight: The inscribed angle of a circle formula states that the measure of an inscribed angle is half the measure of its intercepted arc.

The page presents three important corollaries:

Vocabulary: Corollary One states that two inscribed angles intercepting the same arc are congruent. Vocabulary: Corollary Two establishes that an angle inscribed in a semicircle is a right angle. Vocabulary: Corollary Three declares that opposite angles of an inscribed quadrilateral are supplementary.

The tangent chord theorem is also introduced:

Definition: The measure of an angle formed by a tangent and a chord equals half the measure of the intercepted arc.

Two detailed examples are provided to demonstrate practical applications:

Example: Example One involves finding values of angles 'a' and 'b' using the inscribed angle theorem, where one angle measures 60° and creates an arc of 120°.

Example: Example Two shows how to find an angle formed by a tangent and chord, where mPMQ = 212° and the solution requires applying the tangent-chord theorem to find mLPQR = 74°.

The page concludes with an essential understanding statement:

Highlight: Angles formed by intersecting lines have special relationships to the arcs they intercept, forming the foundation for understanding circle geometry.

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!
