The given two column proof is completed as follows;

Statements ${}$ Reasons

1. $\overline{BE}$ ║ $\overline {CD}$ ${}$ 1. Given

2. ∠1 ≅ ∠2, ∠3 ≅ ∠4 ${}$ 2. Corresponding ∠s Post.

3. ΔABE ~ ΔACD ${}$ 3. AA similarity Postulate

4. $\dfrac{AC}{AB} = \dfrac{AD}{AE}$ ${}$ 4. Def. of ~ Δs

5. AC = AB + BC; AD = AE + ED ${}$ 5. Segment Add. Post

6. $\dfrac{AB + BC}{AB} = \dfrac{AE + ED}{AE}$ ${}$ 6. SAS Similarity Theorem

7. $\dfrac{AB}{AB} + \dfrac{BC}{AB} = \dfrac{AE }{AE} + \dfrac{AE}{AE}$ ${}$ 7. Distributive property of equality

8. $1 + \dfrac{BC}{AB} = 1 + \dfrac{AE}{AE}$ ${}$ ${}$ 8. $Simplify \left(\dfrac{AB}{AB} =1; \dfrac{AE }{AE} =1\right)$

9. $\dfrac{BC}{AB} =\dfrac{AE}{AE}$ ${}$ ${}$ 9. Subtraction prop. of =

Step-by-step explanation:

The given two column proof is completed as follows;

Statements ${}$ Reasons

1. $\overline{BE}$ ║ $\overline {CD}$ ${}$ 1. Given

2. Corresponding angles are congruent (postulate)

3. Angle Angle, AA similarity Postulate

4. Def. of ~ Δs Definition of similar triangles

5. Segment Addition Postulate

6. Side-Angle-Side SAS Similarity Theorem

7. Distributive property of equality

8. $1 + \dfrac{BC}{AB} = 1 + \dfrac{AE}{AE}$ ${}$ ${}$ 8. $Simplify \left(\dfrac{AB}{AB} =1; \dfrac{AE }{AE} =1\right)$

9. Subtraction property of equality, by subtracting 1 from both sides

Note that the right triangles with sides equal to 5, 12, 13 and 9, 12, 13 both have a side equal to 12. using this fact find the

kondor19780726 [428]

There is a mistake 9,12,13 is not a right triangle. but 9,12,15 is. IF you use this triangle instead, then the area of the 13,14,15 triangle is the sum of the area of the other two triangles.
