Identifying Acute, Straight, and Obtuse Angles
In this lesson, the teacher explains the three types of angles: acute, straight, and obtuse. A right angle is equal to 90 degrees and can be represented by a little box. An acute angle is less than 90 degrees, while an obtuse angle is greater than 90 degrees. A straight angle is equal to 180 degrees and can be created by making a line. The teacher demonstrates how to identify each type of angle by including three points to create an angle and provides examples for each type.
Identifying an acute, straight and obtuse angle
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
