Hi, could I have help with these geometry questions regarding triangles? A step by step would be very
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
