When you reflect a diagonal over a line of symmetry, the diagonal will land perfectly on the other diagonal (and vice versa). This suggests that one diagonal is a mirror copy of the other.
Another way to put it: The vertex points of the rectangle will swap when we reflect over a line of symmetry. A diagonal is simply the opposite vertex points joined together. So this is why the diagonals swap places (because the vertices line up perfectly when you apply the reflection).
Answer:
It would be the third answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
The given expression is
We will rewrite the expression
When we add the fraction
= = 8
While Andre says the answer is
because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.
Andre made mistake in this step

Answer:
laps per minute
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>The Pythagorean Theorem is l^2 + l^2 = H^2:</u>
Substituting 12 and 16 as our l's we achieve:
12^2 + 16^2 = 144 + 256
144 + 256 = 400
Square root of 400 = 20
So H or Hypotenuse = 20.
Adding gives us 20 + 12 + 16 = 48 feet.
