Identify the type of angle from a figure acute, right, obtuse, straight ex 1

The video tutorial explains how to identify different types of angles in a geometric figure, including right, straight, acute, and obtuse angles. It provides methods to recognize these angles based on their properties, such as right angles having a 90-degree measure and straight angles forming a straight line. The tutorial also covers how to distinguish between acute and obtuse angles by comparing their measures to right and straight angles. The video concludes with a summary of the identification process.

Which of the following is a characteristic of a right angle?

• It is identified by a small box.
