It looks like you're working on a geometry assignment involving labeling triangles. Although I don't have access to view your triangles or the dropdown options, I can help you understand how to label triangles based on their properties.
-
Based on Angles:
- Acute Triangle: All three angles are less than 90 degrees.
- Right Triangle: One angle is exactly 90 degrees.
- Obtuse Triangle: One angle is greater than 90 degrees.
-
Based on Sides:
- Equilateral Triangle: All three sides are equal in length, and all angles are equal (each 60 degrees).
- Isosceles Triangle: Two sides are of equal length, and the angles opposite these sides are equal.
- Scalene Triangle: All sides are of different lengths, and all angles are different.
For parts 1 and 2, you can use either the angle measurements (if you have them) or the lengths of the sides to label each triangle accordingly. If you share the specific details about the triangles, I can help you more directly with their classifications.
