How many points does a line have?
a line has to have at least 2 points.a plane has to have at least 3 points.______________It takes two points to define a unique line in Euclidean space. But every line and every line segment contains infinitely many points. The same is true for planes in Euclidean space. You need at least 3 points to define a unique plane, but every plane containes infinitely many points and infinitely many lines or line segments.
Do all shapes have edges?
Every shape that is round does not have edges. A shape that has sharp points and has straight lines can have edges.
What is differentiale convex and non-convex?
Take any two points on or inside a body. If every point on the straight line joining the two points lies within the shape, then it is convex. If not, it is non-convex.
Are squares are rhombuses?
Yes. Every square is a rhombus, but not every rhombus is a square.
Is zero a unique number?
Every number is a unique number.
What are the properties of a straight line?
A straight line is a line with the property that, if you pick any two points on the line and connect these points with a straight line, then every point on this new line lies on the original line.

Is it true that every chord of a circle contains two points of the circle?
well its true that every chord contains two points of the circumference of a circle 'cos a chord is the straight line between two points on the circumference
Do all shapes have edges?
Every shape that is round does not have edges. A shape that has sharp points and has straight lines can have edges.
What is a good country?
It depends on what your definition of "good" is. Every country is unique in its own history, culture, food, people, politics and so on. Therefore every country has its own good and bad points.
What is differentiale convex and non-convex?
Take any two points on or inside a body. If every point on the straight line joining the two points lies within the shape, then it is convex. If not, it is non-convex.
Are squares are rhombuses?
Yes. Every square is a rhombus, but not every rhombus is a square.
Same value of the slope between any two points?
Questioning also is a good skill. It must be clear and precise to get the apt answer which will be useful to each and every one. With the nine words put in that way I guess that you mean the slope remains the same every where at all points in between two given points. Is that right? Then the curve in between the two points will be a straight line.
Do you consider the Philippines to be a unique country?
Every country is unique.
Is zero a unique number?
Every number is a unique number.
How many total squares can you make on a standard checker board?
There are 64 single squares, but if you include every square that can possibly be made, there are 204: 1 8x8 square 4 7x7 squares 9 6x6 squares 16 5x5 squares 25 4x4 squares 36 3x3 squares 49 2x2 squares 64 1x1 squares
Does circles has exactly 2 lines of symmetry?
A circle has infinitely many points of symmetry. Every straight line that passes through the center of a circle is a line of symmetry.
