Classifying Triangles Notes

Fun Triangle Worksheets: Discover the 7, 12, or Even 20 Types!

Triangles are fundamental geometric shapes with three sides and three angles. This guide explores the various types of triangles based on their sides and angles, providing clear examples and classifications. Characteristics of different types of triangles are explained, helping students understand how to identify and categorize triangles based on their unique properties.

  • Triangles are classified by both their sides and angles
  • There are three main categories based on sides: equilateral, isosceles, and scalene
  • Angle-based classifications include acute, right, and obtuse triangles
  • Combinations of side and angle properties create various triangle subtypes
  • Examples are provided to illustrate each triangle type and its characteristics

Classifying Triangles by Sides and Angles

This page provides a comprehensive overview of triangle classification, focusing on both side lengths and angle measures. It serves as an excellent resource for students learning about the characteristics of different types of triangles.

Definition: A triangle is a three-sided polygon with three angles.

The page is divided into two main sections: classification by sides and classification by angles.

Classification by Sides:

  1. Equilateral Triangle: All three sides are equal in length.
  2. Isosceles Triangle: Two sides are equal in length.
  3. Scalene Triangle: No two sides are equal in length.

Vocabulary: Equilateral means "equal sides," isosceles means "two equal sides," and scalene means "unequal sides."

Classification by Angles:

  1. Acute Triangle: All angles are less than 90°.
  2. Right Triangle: One angle is exactly 90°.
  3. Obtuse Triangle: One angle is greater than 90°.

Highlight: A triangle can be classified by both its sides and angles simultaneously, leading to combinations like "acute isosceles" or "right scalene."

The page includes several examples of triangles, each labeled with their angle measures and side lengths. These examples demonstrate how to apply both side and angle classifications to real triangles.

Example: Triangle 7 has all angles measuring 60° and all sides equal to 8.6 units, making it an equilateral and equiangular acuteacute triangle.

Other examples include:

  • A right scalene triangle 90°,32°,58°;sides11.2,7,13.290°, 32°, 58°; sides 11.2, 7, 13.2
  • An acute scalene triangle 79°,57°,44°;sides6.1,7.4,8.779°, 57°, 44°; sides 6.1, 7.4, 8.7
  • An obtuse isosceles triangle 26°,26°,128°;sides2.5,2.5,4.526°, 26°, 128°; sides 2.5, 2.5, 4.5
  • An acute isosceles triangle 72°,72°,36°;sides3,4.8,4.872°, 72°, 36°; sides 3, 4.8, 4.8
  • A right isosceles triangle 90°,45°,45°;sides4.8,4.8,6.890°, 45°, 45°; sides 4.8, 4.8, 6.8

This comprehensive guide serves as an excellent classifying triangles worksheet, allowing students to practice identifying triangle types based on given measurements. It effectively covers the 7 types of triangles commonly studied in geometry: equilateral, isosceles, scalene, acute, right, obtuse, and their various combinations.

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.😋🩷🎀

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!
