Question

which pairs of figures are congruent? which pairs are similar?
(first figure: two squares, different sizes)
congruent? ○ yes ○ no
similar? ○ yes ○ no
(second figure: two triangles, same shape, different positions/orientations)
congruent? ○ yes ○ no
similar? ○ yes ○ no
(third figure: a circle and an ellipse)
congruent? ○ yes ○ no
similar? ○ yes ○ no
(fourth figure: two l - shaped figures, different orientations)
congruent? ○ yes ○ no
similar? ○ yes ○ no

Explanation:

Step1: Check congruence/similarity of squares

Two squares (different sizes): Congruent? No (size differs). Similar? Yes (same shape, proportional sides).

Step2: Check congruence/similarity of triangles

Two right triangles (same shape/size): Congruent? Yes. Similar? Yes (congruent implies similar).

Step3: Check congruence/similarity of circle & oval

Circle vs oval: Different shapes. Congruent? No. Similar? No.

Step4: Check congruence/similarity of L-shapes

Two L-shapes (same shape/size): Congruent? Yes. Similar? Yes.

Answer:

Top-left (squares): Congruent? No, Similar? Yes
Top-right (triangles): Congruent? Yes, Similar? Yes
Bottom-left (circle & oval): Congruent? No, Similar? No
Bottom-right (L-shapes): Congruent? Yes, Similar? Yes
