# Triangle Basics Interactive Notes and Practice

Product Description
Review and practice these triangle topics:
-Classifying equilateral, isosceles, and scalene triangles
-Classifying acute, right, and obtuse triangles
-Triangle Inequality Theorem
-Identifying bases and heights to calculate area
-Calculating area on a grid

These middle school geometry topics are important building blocks for high school geometry standards.

Here's why I created this resource...
I teach high school geometry, which requires students to work with triangles a LOT. Students learn trigonometry, congruent and similar triangle theorems, calculate areas and perimeters on a coordinate plane, and more. However, I often had students ask questions about the basics, such as...
Can a triangle be isosceles and right?
I know the area formula, but which measurement is the height?
Do I use the Pythagorean Theorem to determine if three lengths can make a triangle?
How do I count a length on a grid?
None of these are extremely difficult to answer, but they show a lack of understanding that leads to great confusion as the topics get more difficult!

I hope this resource will help your students too, whether they are learning the material as middle schoolers or reviewing in high school.
