To classify the triangles based on their sides and angles, here are the correct classifications:
Triangles based on Sides:
- Equilateral Triangle: Triangle sides of 5 cm, 5 cm, and 5 cm
- Scalene Triangle: Triangle sides of 3 cm, 5 cm, and 7 cm
- Isosceles Triangle: Triangle sides of 3 cm, 5 cm, and 5 cm
Triangles based on Angles:
- Right Triangle: Angles of 40°, 50°, and 90°
- Acute Triangle: Angles of 40°, 60°, and 80°
- Obtuse Triangle: Angles of 40°, 40°, and 100°
You would place each triangle in its corresponding response area based on whether you are classifying by sides or angles.
