Question

Prove that, when two triangles are similar , the ratio of areas of those triangles is equal to the ratio of the squares of their corresponding sides. ( note - take the names of triangle DEF and XYZ .)

Answer 1

Step-by-step explanation:

Now you can compare the ratio of the areas of these similar triangles. This leads to the following theorem: Theorem 61: If two similar triangles have a scale factor of a : b, then the ratio of their areas is a2 : b2. Example 2: In Figure 4 , Δ PQR∼ Δ STU
