Question

determine if triangle pqr and triangle stu are or are not similar, and, if they are, state how you know. (note that figures are not necessarily drawn to scale.) answer attempt 1 out of 2 the triangles similar.

Explanation:

Step1: Check side - length ratios

Calculate the ratios of corresponding sides. $\frac{PQ}{ST}=\frac{16}{64}=\frac{1}{4}$, $\frac{QR}{TU}=\frac{17}{68}=\frac{1}{4}$, $\frac{PR}{SU}=\frac{18}{74}=\frac{9}{37}$.

Step2: Analyze similarity

Since $\frac{PQ}{ST}=\frac{QR}{TU}
eq\frac{PR}{SU}$, the side - length ratios are not all equal.

Answer:

are not
