Why is it important to label all sides of the triangle in homework problems?

• To practice drawing

• To find the right angle

• To ensure correct identification of sides

• To make the triangle look complete

What should you do if the problem only asks for the hypotenuse?

• Skip labeling the sides

• Guess the sides based on the triangle's shape

• Label all three sides correctly

• Label only the hypotenuse

What is a common mistake students make when labeling triangles?

• Choosing sides without labeling

• Labeling the sides in alphabetical order

• Labeling all sides as hypotenuse

• Forgetting to label the right angle
