Question: If triangle ABC is similar to triangle DEF with a scale factor of 2, and the area of triangle ABC is 50 cm², what is the area of triangle DEF?

Options:

  1. 100 cm²
  2. 200 cm²
  3. 150 cm²
  4. 250 cm²

Correct Answer: 200 cm²

Solution:

The area of similar triangles is proportional to the square of the scale factor. Area of DEF = 50 * (2^2) = 200 cm².

If triangle ABC is similar to triangle DEF with a scale factor of 2, and the area of triangle ABC is 50 cm², what is the area of triangle DEF?
  • Similarity of Triangles – Triangles are similar if their corresponding angles are equal and their sides are in proportion.
  • Scale Factor – The scale factor is the ratio of the lengths of corresponding sides of similar triangles.
  • Area Proportionality – The areas of similar triangles are proportional to the square of the scale factor.
