Two bare tests and nine complete specimens preserved in ethanol were examined for test shape and length of spines relative to adult radial symmetry. The interambulacral and ambulacral regions are labeled following Loven's system (Hyman, 1955).
The N-way Wilkinson power divider/combiner utilizes a circular or radial symmetry and provides isolation and impedance matching.[1] In an N-way Wilkinson hybrid divider arrangement, shown in Figure 1, an RF signal fed into the input port with a source impedance [Z.sub.in] is divided into N equipbase, equi-amplitude signals by way of N transmission lines having an electrical length of one-quarter wavelength ([Lambda]/4) at the operating frequency.
STUDENTS WERE THEN INTRODUCED to the concept of radial symmetry. I explained that radial symmetry is a type of balance where parts of an object or picture radiate or revolve around a central point, like the spokes on a bike wheel or a sliced-up pizza.
Most metazoan body plans can be characterized as having, either elements of radial symmetry (such as the Chidaria and Ctenophora) or bilateral symmetry (e.g., protostomes and deuterostomes).
We then discussed and viewed examples of symmetry, asymmetry and radial symmetry they see around them every day--buildings, furniture, cars, flowers, and more.

Next, we discussed symmetry and radial symmetry. I showed students that in order to create a radially symmetrical drawing correctly, it had to look the same no matter how it was turned.
