Answer: AC= 12 cm
Step-by-step explanation:
Here, ABCD is a square with diagonals AC and BD.
Let E is the intersection point of Diagonals AC and BD.
Since, we know that the lengths of diagonals of a square are same.
Therefore We can say, AC=BD
And we know that,
In the case of square diagonals bisect each other,
That is, BE=ED⇒BD= 2BE.
But, BE= 6 cm (given)
⇒BD=12 cm ⇒AC= 12 cm

Answer:
(2, -4)
Step-by-step explanation:
The rotation of an object <u>turns</u> the object around a <u>fixed point</u> called the center of rotation.
A <u>rotation</u> of 90° counterclockwise means:
A 90° rotation counterclockwise with the origin (0, 0) as the center of rotation.
The rule for a counterclockwise rotation of 90° about the origin is:
(x, y) → (-y, x)
Therefore:
(-4, -2) → (2, -4)
