Who many diagonals does a rectangle have?
2 Pentagon-5 Hexagon - 9 formula diagonals=(n-3)+sum from i=1->i=(n-3) [i] diagonals=(n-3)+1+2+. . .+(n-3) The n-3 is because you cannot draw lines to a same point or adjacent ones. The reason (n-3) is used twice, is because the first 2 points you start to draw from are not connected to each other so they draw all the lines they can. Once you get to the third (assuming you are moving in a circle), the number of lines you can draw is reduced by 1, since that line is already drawn (to the first point). The 4th one now already has a line to the first and second points and so draws 2 less lines.
How do you draw a 415 degree angle?
Use a protractor to draw a 55 degree angle and indicate that the angle needs to be measured once around the circle and then some.
How many non-collinear points are there in one plane?
There are an infinite number of any kind of points in any plane. But once you have three ( 3 ) non-collinear points, you know exactly which plane they're in, because there's no other plane that contains the same three non-collinear points.
How can coordinates help you to find the area of figures on the coordinate plane?
Once you know the coordinates, you can use the distance formula to find the lengths of the sides, then using that, you can find the area.
Draw a flowchart of display odd numbers?
A spreadsheet is ideal to create a list (column) showing an odd number in each cell. Once the column is saved, the data can be used in graphs and flowcharts of any form.
Why does a pair of intersecting lines cross only once?
They only cross once because intersecting lines are only supposed to INTERSECT at one point, hence the name intersecting lines
How many times do two intersecting lines cross?
once
How many times do a pair of intersecting lines cross?
Once.
Can two rays intersect in more than one point?
no the definition is two lines intersecting once
How do you draw a pumpkin?
to draw it you wanna start with an outline. You wanna make it large oval shape and draw lines inside that go up and down. Be sure to make lines inside it. Once you have that done you draw a stem on top. Draw a sorta like twig curved on top. Once that is done you can add a leaf if you like. Once done you can color it do whatever you want on it!
Can lines on different planes be parallel?
Yes, they can. Since three points define a plane, take any two points on one line and a point on the other line, and form the plane with those three points. Once you have that, then use Euclid's test to see if they are parallel. Alternately, if the planes themselves are parallel, then the lines are as well, since they definitely will never intersect.
Why are points lines and planes sufficient?
From the concept of a point, one can define a line. Once the concept of a line is defined, one can define a plane. From the concept of a plane, any higher dimension geometrical object can be defined, e.g. a volume.
When parrarel lines meets?
For most purposes in algebra and geometry, but especially geometry, parallel lines never meet. This should be the answer you give on nearly every question. However, speaking realistically, parallel lines can meet on planes of negative and positive curvature. An example of positive curvature would be a sphere; on a sphere, if you try to draw a triangle, the interior sum would be more than 180degrees and parallel lines would intersect. Similarly, on a plane of negative curvature like that of a surface of a saddle, the sum of the measures of the triangle would be less that 180 degrees and once again parallel lines will intersect.
Does square has more lines of symmetry than a parallelogram?
Yes, because you can draw a square on a page and fold it diagonally, sideways and downwards. A parallelogram can only fold on to itself once.
What is a tangent line with respect to a circle?
A tangent to a circle is a line which touches the circle once. That is, it does not pass through the circle, which would mean intersecting it twice. A way to form a tangent is draw any line from the centre point of a circle to its edge. A line on the edge perpendicular (at 90 degrees to) this line will be a tangent.
What is One of two lines parallel to the equator?
"Zero latitude" is the line closest to the equator, because it's the definition of the equator itself. Once you leave the equator, there's no such thing as the "closest line". Any parallel of latitude you draw, no matter how close it is to the equator, I can always draw one that's closer. There's no 'official' set of lines. You can draw as few or as many lines as you want, wherever you want them.
How do you solve a puzzle that only is allowed to cross the lines once and you cant go through them twice?
If I remember the puzzle correctly, you flip a corner of the paper up and draw on the back side of the sheet over the lines and then bring the pencil back to the front side and go to the end.
