Explanation:

Step1: Recall definitions

Congruent figures have same shape and size. Similar figures have same shape, different size.

Step2: Analyze first pair (circle - ellipse)

Circle and ellipse have different shapes. So, neither congruent nor similar.

Step3: Analyze second pair (triangles)

Triangles have same shape (right - angled), different sizes. So, similar ($\text{Sí}$ for similar), not congruent ($\text{No}$ for congruent).

Step4: Analyze third pair (rectangles)

Rectangles have same shape (rectangular), different sizes. So, similar ($\text{Sí}$ for similar), not congruent ($\text{No}$ for congruent).

Step5: Analyze fourth pair (T - shaped figures)

Shapes are different. So, neither congruent nor similar.

Answer:

First pair: Congruente? No, Semejante? No.
Second pair: Congruente? No, Semejante? Sí.
Third pair: Congruente? No, Semejante? Sí.
Fourth pair: Congruente? No, Semejante? No.
