Shape and Space
Statistics and Probability
If two shapes are similar, one is an enlargement of the other. This means that the two shapes will have the same angles and their sides will be in the same proportion (for example, the sides of one triangle might all be 3 times the length of the sides of the other).
angle A = angle D
In the above diagram, the triangles are similar. EF = 6cm and BC = 2cm . What
is the length of DE if AB is 3cm?
