What is a similarity statement in geometry?

Back

A similarity statement is a mathematical expression that indicates that two figures are similar, meaning they have the same shape but not necessarily the same size. For example, if triangle ABC is similar to triangle DEF, it can be written as ABC ∼ DEF.

What is the value of k if \( \frac{2}{k} = \frac{4}{8} \)?

Back

To solve for k, cross-multiply: 2 * 8 = 4 * k, which gives k = 4.
