Prove that a line that divides two sides of a triangle proportionally is parallel to the third side. Be sure to create and name
sattari [20]

Answer:

Given: A triangle ABC and a line DE parallel to BC.

To prove: A line parallel to one side of a triangle divides the other two sides proportionally.

Proof: Consider ΔABC and DE be the line parallel to Bc, then from ΔABC and ΔADE, we have

∠A=∠A (Common)

∠ADE=∠ABC (Corresponding angles)

Thus, by AA similarity, ΔABC is similar to ΔADE, therefore

AB/AD= AC/AE

⇒AD+DB/AD = AE+EC/AE

⇒1+DB/AD = 1+ EC/AE

⇒DB/AD = EC/AE

Therefore, a line parallel to one side of a triangle divides the other two sides proportionally.

⇒Therefore Proved

Hope this helps!!!

Question
Mademuasel [1]

Answer: F

Step-by-step explanation:

  1. This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
  2. This has no solutions (the left hand sides are the same but the right hand sides have different values)
  3. This has one solution (the first equation givess a fixed value for x)
  4. This has no solutions (same reason as 2)
  5. This has one solution (same reason as 3, just the second equation instead of the first)
  6. This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
