Label the parts of a triangle ex 1

The video tutorial explains how to identify and label angles, focusing on angle one. It covers labeling angles using different notations, identifying the vertex as the common endpoint of two rays, and determining the sides of the angle. The tutorial emphasizes the importance of correctly labeling line segments and provides examples for clarity.

Which of the following is NOT a way to label an angle?

• Using the vertex point

• Using angle numbers

• Using the length of the sides

• Using points that form the angle

What is the vertex of an angle?

• The midpoint of the angle

• The common endpoint where two rays meet

• The longest side of the angle

• The shortest side of the angle

In the example given, what is identified as the vertex?

• Point P

• Point M

• Point D

• Point L

Which of the following is a correct way to label the sides of an angle?

• LP and MP

• LD and MD

• LM and PM

• PL and PM

Why is it important to write lines above the sides when labeling an angle?

• To highlight the vertex

• To show they are parallel

• To differentiate from other angles

• To indicate they are line segments
