Question

Prompt

For triangle

P QR

and triangle

S T U

, 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

P QR

is similar to triangle

S T U

?
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.
