What does A'B'C'D' mean in geometry?
after the original ABCD, the A'B'C'D' means that you have done something to the original points, and they therefore can no longer be called ABCD
How many times can you fold a circle?
A circle is a plane figure of two dimensions and therefore cannot be folded as this would need to be done through a third dimension.
How do you find the radius and the coordinates of the center for each circle?
The answer depends on what information is available and in what form.The simplest solution is to write the equation of the circle in the following form:(x - a)^2 + (y - b)^2 = r^2Hiving done that, the coordinates of the centre are (a, b), and the circle's radius is r.
How do you construct a parallel line?
You place a ruler on a piece of paper and trace both sides. Put the point of your pair of compasses on the line and draw a circle. Then draw another circle, that is the same size, the same way further along the line. You will then be able to use your rule to draw a line that is a tangent to the two circle, and so parallel to your first line. Once you have done this you will realize that you don't need to draw a full circle just a small arc.
How many square feet in a 14 foot round circle?
Well, honey, a 14-foot round circle has an area of about 154 square feet. Just take the radius (half the diameter) which is 7 feet, square it, and multiply by pi. Voila, you've got your answer. Math can be a piece of cake when you just dive in and get it done!
