yes they are because you cant bend both of them like your fingers.
A person can distinguish between the ulnar-radius and the fibula-tibia by looking their placement within the body. The ulnar-radius is found in the forearm, while the fibula-tibia is found in the shin.
Ulna is medial to radius in the forearm and tibia is medial to fibula in the shank. However it is tibia which is homologous to radius (not fibula), because the form of those two bones are the same.
The tibia is connected to the fibula. They are both located on the leg below the knee.

What the tibia is to the fibula
The fibula is lateral to the tibia.
tibia and fibula. radius and ulna
The Tibia and fibula are the only bones connecting knee and ankle. The tibia is the main weight bearing bone. The Fibula provides the top attachments for the muscles which raise the foot pivoting at the ankle. Also muscles for raising and straightening the toes. The Tibia also has the top attachments for the main muscles of the calf which enable one to walk tip-toe with the foot pivoted down at the ankle. Again 'Weight-bearing'. With a smashed Fibula you could still walk if willing. Probably not with a smashed Tibia. Tibia also is a blood cell factory inside the marrow.
Fibula or Tibia?
The femur is the longest, followed by the tibia, fibula, ulna, and radius.
The fibula is located lateral to the tibia. In overall anatomical position, the tibia is medial in the body, and the tibia lateral. Both are located in the lower leg. The tibia articulates with the patella proximally, the fibula laterally, and the talus distally.
The fibula is lateral to the tibia. The fibula is the smaller of the two lower leg bones.
