Given: D is the midpoint of AB; E is the midpoint of AC. Prove: DE || BC
y
A(2b, 2c)
Complete the missing parts of the paragraph proof.
Proof:
To prove that DE and BC are parallel, we need to show
that they have the same slope.
V2-ni c-c
slope of DE = X2 - X1 = a + b - b
slope of BC =
Therefore, because
DE || BC.
D(b, c)
Ela + bc)
B(0,0)
C(2a, 0)
