Question

which pairs of figures below are congruent?
grid with two circles (small and large), two triangles (different sizes), two l - shaped figures (different positions/sizes? wait, no, looking at the ocr: first row left: small circle and large circle; first row right: small right - angled triangle and large triangle; second row left: two l - shaped figures (maybe same shape different positions?); second row right: two rectangles. each pair has yes or no radio buttons.

Explanation:

Step1: Analyze first pair (circles)

Congruent figures have same shape and size. The two circles have different sizes (radii), so not congruent. Choose "No".

Step2: Analyze second pair (triangles)

One triangle is right - angled, the other is equilateral - different shapes and sizes. Not congruent. Choose "No".

Step3: Analyze third pair (L - shaped figures)

The two L - shaped figures have same shape and size (can be translated/rotated to match). So congruent. Choose "Yes".

Step4: Analyze fourth pair (rectangles)

The two rectangles have same shape and size (length and width appear equal). So congruent. Choose "Yes".

Answer:

First pair (circles): No
Second pair (triangles): No
Third pair (L - shapes): Yes
Fourth pair (rectangles): Yes
