+## Analytical Geometry
+
+### Question 1 a)
+
+Lets first find each of the side lengths to determine if the triangle is **obtuse**, **acute** or scalene.
+
+$`AB = \sqrt{(-1-7)^2 + (5-2)^2} = \sqrt{64 + 9} = \sqrt{73}`$
+
+$`BC = \sqrt{(7-(-1))^2 + (2-(-4))^2} = \sqrt{64 + 36} = \sqrt{100} = 10`$
+
+$`AC = \sqrt{(-1-(-1))^2 + (5-(-4))^2} = \sqrt{0^2 + 9^2} = \sqrt{81} = 9`$
+
+$`\since
