Lesson Objective

Identify triangles by their angles.

You have already learned different types of angles.

Right angle

Acute angle

Right Triangle- one right angle

Obtuse Triangle- one angle greater than a right angle

Acute Triangle- three angles less than a right angle

Right Triangle

Acute Triangle

Right Triangle

Obtuse Triangle

• Understanding different types of triangles will help you with passing the district and state test.

• If you want to get a job as a builder you need to know the different types of triangles that would work for different structures

Steps:

• Look at the triangle.

• Ask does this triangle make a right angle? (if yes then you have a right triangle, if no continue)

• Ask is the triangle smaller or bigger than a right triangle? If smaller than you have an acute triangle, if bigger than you have an obtuse triangle.

• What was our objective for the day?

• Why is it important to learn about different triangles?

• What is this triangle called?
