Congruent PPT of graphics, part 2: classic examples

[Example 1] Among the following figures, which one is congruent with the known figure is ()

[Example 2] As shown in the figure, after folding △ABC along AC, point B and point E coincide, then the congruent triangles in the figure have ()

A.1 pair B.2 pair C.3 pair D.4 pair

[Example 3] As shown in the figure, △ACD≌△CBE, point out the corresponding sides and corresponding angles.

Solution: Corresponding sides: AC and CB, CD and BE, AD and CE;

Corresponding angles: ∠A and ∠BCE, ∠ACD and ∠B, ∠D and ∠E.
