Questions & Step-by-Step Solutions
In a circle, if a tangent is drawn from a point outside the circle, what is the relationship between the tangent and the radius at the point of contact?
Step 1: Understand what a tangent is. A tangent is a straight line that touches a circle at exactly one point.
Step 2: Identify the point where the tangent touches the circle. This point is called the point of contact.
Step 3: Know that a radius is a line segment that connects the center of the circle to any point on the circle.
Step 4: Draw a radius from the center of the circle to the point of contact where the tangent touches the circle.
Step 5: Observe the angle formed between the tangent line and the radius at the point of contact.
Step 6: Remember that the relationship between the tangent and the radius at the point of contact is that they meet at a right angle (90 degrees).
Step 7: Conclude that the tangent is perpendicular to the radius at the point of contact.
