Describe the symmetry of the figure. Identify lines of symmetry, if any. Find the angle and the order of any rotational symmetry

Sophie [7]

Answer:

see below

Step-by-step explanation:

Clearly, if you turn the figure sideways or upside down (rotate 90° or 180°), you do not have the same figure. It has no rotational symmetry.

However, if you reverse it left-to-right, you get exactly the same figure. So, it has line symmetry about a vertical center line.

Find the perimeter of rectangle whose length is 40 and the diagonal is 41 cm<br>

Bond [772]

Answer:

Step-by-step explanation:

Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.

$L=40\, cm\\D=41\,cm\\W=\ ?\\\\W^2+L^2=D^2\\\\W^2+40^2=41^2\\\\W^2+1600=1681\\\\W^2=81\\\\W=9$

Perimeter:

P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98
