Lines can be positioned in different ways. They can be straight or curved, and they can be horizontal, vertical, or diagonal. Two lines can also be positioned in different ways in relation to each other. They can be parallel (like train tracks), meaning they never meet or cross each other. They can also be perpendicular (like the corners of a square), meaning they meet at a right angle (90 degrees). Lines can also intersect, which means they cross each other at a certain point.
A tangent line to a circle is a line that just touches the circle at one point. It is like a straight line that is "kissing" the circle at one point. This point is called the point of tangency. If we draw a line from the center of the circle to the point of tangency, that line will be perpendicular to the tangent line. For example, if we have a circle and draw a tangent line to it, we can draw a line from the center of the circle to the point of tangency, and that line will be perpendicular to the tangent line.
Circles are another type of shape in geometry. They are round and have no corners. They are made up of points that are all the same distance from the center of the circle. We can describe the position of a circle in terms of its center point and its radius. The center point is the point at the exact center of the circle. The radius is the distance from the center point to any point on the circle.
Points are like tiny dots in space. We use points to describe the position of things in geometry. A point can be located on a circle, meaning it is exactly the same distance from the center of the circle as all the other points on the circle.
When we talk about a point located inside a circle, we mean that the point is located within the boundaries of the circle. This means that the distance from the point to the center of the circle is less than the radius of the circle. For example, if we have a circle with a radius of 5cm and a point located inside the circle that is 3cm away from the center of the circle, then that point is located inside the circle.
On the other hand, if a point is located outside a circle, it means that the point is located outside the boundaries of the circle. This means that the distance from the point to the center of the circle is greater than the radius of the circle. For example, if we have a circle with a radius of 5cm and a point located outside the circle that is 7cm away from the center of the circle, then that point is located outside the circle.
When we talk about the position of points, lines and circles in relation to each other, we can describe them in terms of how they intersect or how they are positioned in relation to each other. For example, a line can be tangent to a circle, which means it just touches the circle at one point. Or a line can intersect a circle at two points, creating what is called a chord.
