The task in the image is to "name" the triangles shown, likely referring to classifying them based on their shapes or angles. Here is the classification:

1. Top-left triangle: This appears to be an isosceles triangle (two sides are of equal length).
2. Top-right triangle: This is also an isosceles triangle based on its symmetry.
3. Bottom-left triangle: This is a scalene triangle (all sides of different lengths).
4. Bottom-right triangle: This is a right triangle (has one 90-degree angle).

Would you like more detailed explanations or drawings for any of these classifications?

4. How can you confirm if a triangle is a right triangle using its sides?
5. What role does the Pythagorean theorem play in classifying triangles?

Tip:

To classify triangles effectively, observe their angles (acute, right, obtuse) and sides (equal or unequal lengths).
