Solution
Solution Steps
Step 1: Identify corresponding sides
The large triangle has sides 15, 10, and an unknown length. The smaller, yellow triangle has sides 6, 4, and an unknown length.
Step 2: Check for Similarity
We see that the ratio of corresponding sides is:
\( \frac{15}{6} = \frac{5}{2} \)
\( \frac{10}{4} = \frac{5}{2} \)
Since two pairs of corresponding sides are proportional, and the included angles are congruent (marked with the same symbol), the two triangles are similar by SAS (Side-Angle-Side) similarity.
