are these shapes similar?\n\nyes\nno

Explanation:

Step1: Check angle congruence

All angles of both shapes are $90^\circ$, so all corresponding angles are congruent.

Step2: Check side proportionality

Calculate ratio of sides: $\frac{17}{20} = 0.85$. All corresponding sides have this same ratio.

Step3: Verify similarity criteria

For polygons to be similar, all corresponding angles must be congruent, and all corresponding sides must be in proportion. Both conditions are met.

Answer:

yes
