user: What is the sum of angles in a triangle?

assistant: We usually look at this in a two-dimensional cartesian space , also referred to as 'euclidian geometry'. In that case the sum of angles in a triangle is always 180 degrees.
There are other geometries where this is not necessarily the case. For example in a three dimensional space that is formed as a ball you can have have triangle on the surface of teh ball where the sum of angles is 270 degrees.

user: What are all the different types of alpaca breeds?

assistant: The alpaca comes in two breeds, Suri and Huacaya, based on their fibers rather than scientific or European classifications.

Huacaya alpacas are the most commonly found, constituting about 90% of the population. The Huacaya alpaca is thought to have originated in post-colonial Peru. This is due to their thicker fleece which makes them more suited to survive in the higher altitudes of the Andes after being pushed into the highlands of Peru with the arrival of the Spanish.

Suri alpacas represent a smaller portion of the total alpaca population, around 10%. They are thought to have been more prevalent in pre-Columbian Peru since they could be kept at a lower altitude where a thicker fleece was not needed for harsh weather conditions.
