Question

12-8 Congruent and Similar SolidsDetermine whether each pair of solids is similar, congruent,or neither. If the solids are similar, state the scale factor.Number 40 only

Answer 1

If two solids are similar, then the ratios of their corresponding sides are equal.

Notice that the side marked 2m is corresponding to the side marked 6m.

Also the vertical height marked 2m is corresponding to the vertical height marked 5m.

So the ratio of the corresponding sides are:

`\begin{gathered} (6)/(2),(5)/(2) \\ 3,2.5 \end{gathered}`

In this case, the ratio of the corresponding sides are not equal.

Hence, the solids are neither similar nor congruent
