# In Δ A B C , the midpoints of the sides are joined. (a) what does intuition suggest regarding the relationship between Δ A E D and Δ F D E ? (We will prove this relationship later.) (b) what does intuition suggest regarding Δ A E D and Δ E B F . To determine

a)

To explain:

The intuition regarding the relationship between ΔAED and ΔFDE.

Explanation

Given:

The given figure is shown below.

Approach:

As per given information, the mid-points of the sides are joined in ΔABC. So triangles formed by joining the midpoints will be of equal sides.

Therefore, by SSS postulate, all the four smaller triangles inside ΔABC are congruent

To determine

b)

The intuition regarding the relationship between ΔAED and ΔEBF.
