Idk if this makes sense but,
You can prove it by SSS [3 sides of given triangles are congruent
<span>Proof: Since the given figure is parallelogram then the two opposite sides are congruent </span>
<span>AB=CD & AD=BD </span>
<span>and obviously the diagonal of a parallelogram are the common sides of the two triangle then they are congruent </span>
<span>therefore triACD is congruent to triABC by SSS Postulate</span>

Answer: 3y - x - 42 = 0
Step-by-step explanation:
The equation y + 1 = -3(x - 5)
Now expand the expression by opening the brackets
y + 1 = -3x + 15
Recall,
Equation of line , y = mx + c , where m = slope
rearranging the equation above in order to determine the ( m)
y = -3x -1 + 15
y = -3x + 14
Recall again condition for perpendicularity
m₁m₂ = -1
From the equation given, m₁ = -3, therefore , to get m₂
-3 x m₂ = -1
-3m₂ = -1
Therefore m₂ = -1/-3
m₂ = 1/3
Now , to find the equation of the second line parallel to the first one,
Just replaced the -3 in the equation above by m₂ = 1/3 in
y = -3x + 14
y = x/3 + 14
Now , multiply both the RHS and LHS of the equation by 3, to make it a linear.
3y = x + 3 x 14
3y = x + 42
3y - x - 42 =0
