Answer:
90° degrees
Step-by-step explanation:
the angle of rotational symmetry for a square is 90 degrees.
which the figure can be rotated to coincide with itself. The order of symmetry is the number of times the figure coincides with itself as its rotates through 360° .
example: a regular hexagon has rotational symmetry.
It’a the third , and can I have the brainliest too
The first claim,
"If 2<em>n</em> + 4 is even, then <em>n</em> is even"
is false; as a counterexample, consider <em>n</em> = 1, which is odd, yet 2•1 + 4 = 6 is even.
The second claim,
"If <em>n</em> is even, then (<em>n</em> + 3)² is odd"
is true. This is because
(<em>n</em> + 3)² = <em>n</em> ² + 6<em>n</em> + 9
<em>n</em> ² + 6<em>n</em> is even because <em>n</em> is even. 9 is odd. The sum of an even and odd integer is odd.
Answer: screenshot below
Step-by-step explanation:
-1 means 1 space left from 0 on the x axis
5/2 means 5/2 spaces above 0 on the y axis
i converted 5/2 to 2 1/2 to make it easier and plotted the point by drawing a line from -1 and 2 1/2 (this is not needed for the showing of the answer)
the point is where the lines connect, aka (-1, 5/2)
