Did you know?

The red deer is Scotland’s largest deer. Males (stags) have large, branching antlers that increase in size as they get older. These impressive antlers can measure up to one metre across and weigh as much as 15 kilograms. During the breeding season, males use their antlers when battling each other.

Whiteboard Challenges

Look closely at the antlers of this red deer, and you’ll see lots of angles.

1) Can you see an angle that is close to a right angle?

2) How many acute angles can you see?

3) How many obtuse angles can you see?
