Scale factor = 2
Step-by-step explanation:
Answer:
Side MQ is similar to side MR.
- This is because since M is the mid point of QR, both MQ and MR are half of QR.
Angle MXQ and MYR are 90°
Sides QX and RY are similar.
- This is because angle X and Y are 90° and MQ and MR are equal.
∴ MQX is congruent to MRY.
