Which of the following would be a line of reflection that would map ABCD onto itself?

Lady bird [3.3K]

When a shape is rotated, it must be rotated over a line.

<em>The square must be reflected over line </em> $x +y = 4$ <em>, for it to be mapped onto itself.</em>

<em />

<u>The points are given as:</u>

$A = (3,1)$

$B = (3,3)$

$C = (1,3)$

$D = (1,1)$

To map the square onto itself, it must be reflected over its diagonal

The diagonals of the square are: AC and BD

<u>Using AC, we have:</u>

$A = (3,1)$ ---- $(x_1,y_1)$

$C = (1,3)$ ---- $(x_2,y_2)$

Start by calculating the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

So, we have:

$m = \frac{3-1}{1-3}$

$m = \frac{2}{-2}$

$m = -1$

The equation is then calculated as:

$y = m(x - x_1) + y_1$

This gives:

$y = -1(x - 3) + 1$

$y = -x + 3 + 1$

$y = -x + 4$

Rewrite as:

$x +y = 4$

So, the square must be reflected over line $x +y = 4$ , for it to be mapped onto itself.

See attachment for square ABCD and its line of reflection.

T = 130°

U = 115°

V = 65°

because things on a line equal 180°, so you would subtract 180 by the number to get the full line, and letters across from the other, Like V and the space to the right of 115° would be the same

An observatory is shaped like a cylinder standing on one of its bases with a dome on top.The diameter of the floor of the observ

Ratling [72]

Answer:

$200.96\ ft$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$

in this problem

$D=64\ ft$

substitute

$C=\pi (64)=64\pi\ ft$ -----> exact value of the circumference

Find the approximate value of the circumference

assume

$\pi=3.14$

$64\pi\ ft=64(3.14)=200.96\ ft$
