T2W8 Quiz

Four sided shapes are a topic of great interest to humans. They have a unique balance between form and function - so much so that we will try to use them wherever we can in life (even when they don't naturally occur that way - such as 'square' watermelons!).

The topic of next week's quiz is sufficiency conditions for quadrilaterals. This is all about how to prove that a given shape is a specific type, or conversely, what you can know about a given shape if it is known to be a specific type. As a reminder, be very careful when you are constructing diagrams - make sure you don't make something geometrically impossible! (Tip: get a couple of friends to check your question before you submit it - if they can both get different solutions, then you may have a problem on your hands.)

P.S. Here is the List of Shame for overdue Circle Solutions. If you haven't submitted yet, then finish your answer and upload it in the template provided!
