a) The vertices of a triangle are J(-2,2), K(-1,-3), and L(5,1).

i) is triangle JKL an equilateral, isosceles, or scalene triangle?

ii) Determine the perimeter of JKL

b) A(5,9), B(-3,3), and C(7,-5) are the vertices of a triangle. M is the midpoint of AB and N is the midpoint of AC.

i) Calculate the coordinates of M and N

ii) Show that MN is parallel to BC and half of BC
