Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25
then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm

The equation that does not justify the similarities of both triangles is:

<h3>Similar triangles</h3>
Similar triangles may or may not have congruent sides.
The triangles are given as:
The above means that, the following sides are similar
- Line segments PQ and ST
- Line segments QR and TR
- Line segments PR and SR
So, the equation that does not justify the similarities of both triangles is:

Answer:
Radius
Step-by-step explanation:
CB = AB/2
Since AB is the diameter, CB is a radius
