Saying that two triangles are similar means that they have the same angles. It also means that the sides are in the same proportions. For example if a triangle's sides have lengths 18, 24 and 32, a similar triangle might have sides of lengths 36, 48 and 64, or sides of lengths 48, 36 and 27. I'm not sure what you meant by "trapezium in similar triangles".
