### Little Red Riding Hood needs help!

### Where to meet?

The location of the houses of three friends, Antonio, Benedict and Celine happened to form an equilateral triangle. They meet quite often to catch up with each other; however, none of them want to invite their friends home. To be fair, they decided to meet at a place that is most 'central' to all.

• What would you suggest?
• How would you do it if you have their houses marked on a map already?

Note: There is a typo-error in the above diagram, it should be "Benedict"
