It seems you are working on an exercise related to labeling triangles based on their classifications. While I can guide you through the process of classifying triangles, it sounds like you're looking for interactive tools (like a protractor and ruler) that I can't access. However, I can explain how to identify the triangles by their properties!
Part 1: Classifying Triangles by Angles
- Acute Triangle: All angles are less than 90 degrees.
- Right Triangle: One angle is exactly 90 degrees.
- Obtuse Triangle: One angle is greater than 90 degrees but less than 180 degrees.
Part 2: Classifying Triangles by Sides
- Equilateral Triangle: All three sides are of equal length.
- Isosceles Triangle: Two sides are of equal length, and the third side is a different length.
- Scalene Triangle: All sides are of different lengths.
To label each triangle correctly:
- Measure the angles with the protractor and choose the appropriate name based on angle classification.
- Measure the lengths of the sides using the ruler and choose the name based on side classification.
If you have specific measurements or details about the triangles you're working with, feel free to share them, and I would be happy to help you classify them!
