Answer:

Step-by-step explanation:
ΔTQR and ΔTRS are similar (AA). Therefore the sides are in proportion:

We have QT = 5m ans TS = 22m. Substitute:
<em>cross multiply</em>


Answer:
The distance between any two corresponding points on ΔXYZ and ΔX'Y'Z′ is equal to 
Step-by-step explanation:
we know that
To find the distance, apply the Pythagoras Theorem
Let
x ----> the distance between any two corresponding points on ΔXYZ and ΔX'Y'Z′
