The video tutorial explains how to construct acute and obtuse angles using a set of points. It emphasizes the importance of correctly identifying the angle being measured by the tool, ensuring the angle is less than 90 degrees for acute angles and greater than 90 but less than 180 degrees for obtuse angles. The tutorial provides step-by-step guidance on selecting the vertex and positioning the rays to form the desired angles.

What is the defining characteristic of an acute angle?

• It is more than 180 degrees.

• It is exactly 90 degrees.

• It is less than 90 degrees.

• It is exactly 180 degrees.
