in triangle abc points dand e are the midpoints of ab and ac respectively. what are the slope and length of dë, if the slope and length of bc
are 0.5 and 3.2 units, respectively?
a slope = -2, length = 3.2 units
b. slope = 0.25, length = 3.2 units
c. slope = 0.5, length = 1.6 units
d. slope = -2, length = 1.6 units
e slope = 0.25, length = 1.6 units

C. slope = 0.5, length = 1.6 units

Step-by-step explanation:

See the diagram attached.

D is the midpoint of AB and E is the midpoint of AC.

Therefore, DE will be parallel to BC.

Hence, Slope of BC =Slope of DE =0.5. (Answer)

Now, ΔADE and ΔABC are congruent.

{Since BC║DE, then ∠ADE =∠ABC and ∠AED =∠ACB and ∠A is common.}

So,

Therefore, DE = = = 1.6 units. (Answer)
