When water percolates down through the soil

Nitrogen is an essential plant nutrient, especially for growth. Some plants require more nitrogen than others.

All regular polygons

A polygon is symmetrical if its sides that cross the line of symmetry are halved by the line of symmetry and if the sides that do not cross the line of symmetry have the same positions in space, the same lengths, and the same angles with their neighboring sides as do the sides on the other side of the line of symmetry. The only symmetrical triangles are isosceles triangles (equilateral triangles are isosceles). The only symmetrical quadrilaterals are squares, rectangles, rhombi (the line of symmetry connects either pair of opposite corners), isosceles trapezoids, and kites.

False

Yes, you can bisect an angle using the paper folding technique.

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.

No. It is possible to fold an angle on paper to bisect it.

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.

56 (: When we say polygon abcd is similar to polygon afge, they already told you which are the lines that are similar. ab:af=bc:fg=cd:ge etc. Lines ad and af are not similar in length and therefore cannot be used to find perimeter of polygon abcd even though the perimeter of polygon afge is given.

16. 8 through pairs of opposite vertices and another 8 through the midpoints of opposite sides.

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

You can construct a parallel to a line through a point not on the line.

(perpendicular line segment)

The following is the answer.

An equilateral triangle has 60 degree angles. 60 degrees x 6 = 360 degrees. A hexagon has 6 sides so....

Compass I know that apex struggle

No.

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