Question

△jkl and △mno are shown below.
which statement is true?
△jkl is similar to △mno.
△jkl is not similar to △mno.
there is not enough information to determine whether the triangles are similar.

Explanation:

Similar triangles require either two pairs of congruent corresponding angles (AA similarity), three pairs of proportional corresponding sides (SSS similarity), or two pairs of proportional corresponding sides with the included congruent angle (SAS similarity). The diagram only shows one pair of congruent angles ($\angle L \cong \angle O$) with no information about side lengths or other angles.

Answer:

There is not enough information to determine whether the triangles are similar.
