(a)

Segment $\"\"$ is parallel to Segment $\"\"$ .

$\"\"$ and $\"\"$ by the property of transversal.

From AA property of similar triangles, $\"\"$ .

Therefore, $\"\"$ .

(b)

Length of sides are $\"\"$ , $\"\"$ and $\"\"$ .

Side-Splitting theorem : if Segment $\"\"$ Segment $\"\"$ , then $\"\"$ .

$\"\"$

Therefore $\"\"$
