Answer:
Let name the two triangles as ΔABC and ΔP QR.
Length of corresponding sides of two triangles are proportional.
[tex]\frac{QR}{AB}=\frac{PR}{AC}=\frac{PQ}{BC}\\\\\frac{4}{8}=\frac{3}{6}=\frac{2}{4}=\frac{1}{2}[/tex]
So, by Side-Side-Side , Similarity Axiom of two triangles
ΔBAC~ ΔQRP →[SSS]
The two sets of angles which are corresponding angles
Option B: ∠p and ∠s; ∠q and ∠r
The reason being that if two triangles are similar ,their corresponding angles are equal.
