Question

Prompt

For triangle PQR and triangle STU, angles P and S each measure

3 0^{\circ}

QR = 16

and

T U = 12

. Which additional piece(s) of information is(are) sufficient to prove that triangle PQR is similar to triangle STU?

I. The length of

\overline{P Q}

\frac{4}{3}

the length of

\overline{S T}

II. The length of

\overline{P R}

\frac{4}{3}

the length of

\overline{S U}

I is sufficient, but II is not.

II is sufficient, but I is not.

I is sufficient, and II is sufficient.

Neither I nor II is sufficient.
