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:

Step1: Identify triangle types

$\triangle JKL$ has all sides marked congruent, so it is an equilateral triangle. All its angles are $60^\circ$.
$\triangle MNO$ is a right triangle ($\angle N = 90^\circ$), with one unmarked acute angle at $O$.

Step2: Compare angle sets

For triangles to be similar, all corresponding angles must be equal. $\triangle JKL$ has no right angle, while $\triangle MNO$ has a $90^\circ$ angle. Their angle sets cannot match.

Answer:

$\triangle JKL$ is not similar to $\triangle MNO$.
