Question

Show that angle a equals angle c euqals angle e equals angle g
<a=<c=<e=<g
Please explain why all these angles are equivalent. You can use a proof if you like.

Answer 1

whilst k and i are parallel to each other, opposite angles are equivalent (F and H, for example, are the same).

and so if there is one angle given, it is plausible to find the angle of the rest; that would happen due to the usage of F and Z shapes (F and B are the same; D and H are the same)
