How do you know if a figure is symmetric about the line of symmetry?
A figure is symmetric about a line of symmetry if it can be folded along that line, and both halves match perfectly. This means that for every point on one side of the line, there is a corresponding point at the same distance on the opposite side. Additionally, you can check symmetry by reflecting points across the line; the reflected points should lie on the figure itself. If both conditions are satisfied, the figure is symmetric about the line.
A figure formed by three or more points joined by line segments?
Triangle: A figure formed by exactly three (non-colinear) points joined by line segments is a triangle. A figure formed by three or more points is generally called a polygon. Of course, if all of the points are co-linear then there is not much of a figure. A polygon has 3 or more sides.
What are the figures that match exactly when folded in half have?
Line Symetry
A line that divides a figure into 2 matching parts when it is folded?
A line of symmetry, or axis of symmetry.
When the figure can be folded on this line so that its 2 halves match?
axis of symmetry

If a figure can be folded along a line so that both parts match perfectly what is it called?
Is a line of symmetry
A tangent line is a line that intersects a circle at exactly two points?
No. A tangent touches the circle at exactly one point. A line that intersects a circle at exactly two points is a secant.
How many points determine exactly one line?
It takes exactly 2 distinct points to uniquely define a line, i.e. for any two distinct points, there is a unique line containing them.
What geometric figure consisting of two points on a line and all the points between them?
line segment
What is a figure that has no end points?
A straight line other than a line segment which does have end points.
Through any three points not on a line there is one?
between two point there is exactly one line between three points there is exactly one plane
2 points determine exactly one?
line
