Identifying Right Triangles

In our Identifying Right Triangles lesson plan, students learn about right, acute, and obtuse triangles. Students practice identifying whether triangles are right, acute, or obtuse and answer questions about the attributes of each type.


Our Identifying Right Triangles lesson plan teaches students what right triangles are and how to identify them. Students also learn about obtuse and acute angles. During this lesson, students are asked to answer both true or false and short answer questions about right triangles. Students also practice identifying whether a triangle is a right triangle, obtuse, or acute in order to demonstrate their understanding of the lesson material.

At the end of the lesson, students will be able to recognize right triangles as a category and identify right triangles.
