We apply the formula of distance between points:
 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
 We have then:
 For WX:
 WX = root ((- 3 - (- 10)) ^ 2 + (- 1-4) ^ 2)
 WX = 8.602325267
 For XY:
 XY = root ((- 5 - (- 3)) ^ 2+ (11 - (- 1)) ^ 2)
 XY = 12.16552506
 For WY:
 WY = root ((- 5 - (- 10)) ^ 2+ (11-4) ^ 2)
 WY = 8.602325267
 The triangle is isosceles because it has two equal sides.
 Answer:
 WX = 8.60
 XY = 12.17
 WY = 8.60
 Isosceles
