Answer 1

Assuming the triangle ABC is equal to the triangle QRS means that their sides will have the same size.
So the side AB is the same as QR. As well as BC is the same size as RS; AC is the same as QS.
So, if AB = QR that means that both have 50 cm.
Answer: 50 cm

Answer 2

The scale factor between the two triangles is 10. ΔABC has sides that are 10times larger than those of ΔQRS. I found the scale factor first by diving similar sides. 60/6=10. I then found side QR by dividing the length of side AB by 10. 50cm/10= 5cm.

ANSWER: Side QR measures 5cm in length.
