 Hi and welcome to the session. Let us discuss the following question. Question says fill in the blanks. Second part is a line intersecting a circle in two points is called a dash. Let us now start with the solution. We know tangent intersects the circle only at one point. Now let us discuss what is a secant. A secant to a circle is a line that intersects the circle at two points. You can see we are given a circle with center O and PQ is a secant intersecting the circle at two points. We can name these points as A and B. Now we get a line intersecting a circle is called a secant. So we can fill in this blank secant. So this is our required answer. This completes the session. Hope you understood the solution. Take care and have a nice day.
