The first one is GH Segment.
Both shapes are similar. The figure on the right is a scaled version of the figure on the left. The VU edge in the left figure corresponds to the GH edge in the right figure.
The second one is %
.
As can be seen, the VU edge is
units long while the GH edge is
units long. By proportioning these edges and multiplying by
, we find the scaling factor. It is
.
