Answer:
The true statements are 1, 2 and 3.
Step-by-step explanation:
Given information: [tex]\triangle ABC\sim \triangle PQR[/tex].
Two triangles are called similar triangles if their corresponding sides are proportional or corresponding interior angles are equal.
It is given that [tex]\triangle ABC\sim \triangle PQR[/tex], so we get
[tex]\angle A=\angle P[/tex]
[tex]\angle B=\angle Q[/tex]
[tex]\angle C=\angle R[/tex]
[tex]\frac{AB}{PQ}=\frac{BC}{QR}=\frac{AC}{PR}[/tex]
Therefore options 1, 2 and 3 are correct.
The corresponding sides of similar triangles are proportional but not congruent, therefore options 4 and 5 are incorrect.
