Question

The kite has vertices D(0, u), G(-w, 0), and F(0, -2u).

What are the coordinates of E?
(w, 0) (w, 2u) (0, -u) (0, w)

Answer 1

Answer: (w,0)

if you didnt understand the answer above,

or if its tldr

Answer 2

Diagonal DF (and y-axis) is the line of symmetry, so point E is the reflection of point G through DF (or y-axis) and its coordinates are (w,0).
