What tools did the Greeks not use in geometric constructions

Tracing paper, ruler.

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is lying in its plane

True APEX

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point of symmetry

False

A line has rotational symmetry

two-fold

A point of symmetry divides a design so that every point on one side coincides with a point on the other side

False

A point of symmetry is a point around which a shape can be rotated without changing any of its characteristics

If it says rotated it's true

If it says reflected it is false

What does fbao mean

foreign body airway obstruction

Should you perform CPR on a casualty experiencing cardiac arrest

If they meet the criteria of no signs of life, then yes you would immediately start CPR. If the person experiencing cardiac arrest is breathing and has a pulse, then other measures are necessary.

To find a segment parallel to another segment through a given point using paper folding techniques

Fold the paper so the line is on itself.

Fold this folded edge on itself causing a crease to form that goes through the point in question,

You are using the theorem that lines perpendicular to the same line are parallel.

What do you do if you see your friend turn into a werewolf

Run Away

Does T have rotational symmetry and line symmetry

It has line symmetry (straight down the center) but not rotational symmetry.

Is it true that a shape with rotational symmetry can be rotated around a point so that all of its characteristics are maintained

It only has rotional symmetry if it can be rotated around a point less than 360 degrees and staying the same shape like if you rotate a square 90 degrees it will be the same shape as in the beginning.. Kind of confusing

What symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in its plane

Reflectional symmetry

Which of these tools or constructions is needed to construct an equilateral triangle

Compass I know that apex struggle

Does the parallel postulate in Euclidean geometry work in spherical geometry

No.

What does not describe a rigid motion transformation

Stretch

Which of the following describes a rigid motion transformation A enlarging a photo B spinning a spinner C filling a tire with air D slicing a log into sections

Spinning a spinner.

What kinds of regular polygns can be used for regular tessallations

Squares and equilateral triangles will tessellate leaving no gaps or overlaps.

Which transformations will result in an image that maps onto itself

Rotate 360 degrees

What is One way to recognize a line of symmetry is to look for a line that divides the original image into

two congruent parts

All regular polygons have four sides

False because only 4 sided quadrilateral regular polygons have 4 sides such as squares.

A line segment that forms a right angle with another segment at its midpoint is a

Perpendicular Bisector
