Answer:
a) the triangles are similar triangles because they are the same shape. The angles in both triangles have the same value.
b) The similarity ratio between the two triangles is 0.5, because the lengths of the sides of the triangle on the right are double the value of the lengths of the sides of the triangle on the left.
c) angle U = angle G. angle V = angle H. angle T = angle F.
UV/GH = VT/HF = TU/FG = 0.5
