Let D, E and F be the midpoints of the sides BC, CA and AB respectively of a triangle ABC. Triangle DEF is congruent to which of the following triangles?<br>1. AEF<br>2. FBD<br>3. EDC<br>Select the correct answer using the code given below.
- A. 1 only
- B. 2 and 3 only
- C. 3 only
- D. 1, 2 and 3 ✓
Correct Answer: D. 1, 2 and 3
Explanation
Joining the midpoints of the sides of a triangle divides it into four mutually congruent triangles. Therefore, \Delta DEF is congruent to \Delta AFE, \Delta FBD, and \Delta EDC.
