State true or false: If all the corresponding angles of two triangles are the same, then the two triangles are necessarily congruent.
False
If all the corresponding angles of two triangles are equal, then triangles have the same shape, but not necessarily the same size and hence may not be congruent. See the figure below. The corresponding angles of both triangles are equal, but still their sizes are not the same and hence they are not congruent.
