Web24 Oct 2024 · CBSE Class 10 Maths Notes Chapter 10 Circles. Circle: A circle is a collection of all points in a plane which are at a constant distance from a fixed point. Centre: The fixed point is called the centre. Radius: The constant distance from the centre is called the radius. Chord: A line segment joining any two points on a circle is called a chord. WebNotes: This is all to do with pi and why it is such an important number. From finding the circumference and area of circles to problem solving and investigation. Pupils will begin by learning the names of the parts of a circle then, either through investigation or practical activity, discover that the circumference of a circle is always just a ...

WebParts Of A Circle. The following video gives the definitions of a circle, a radius, a chord, a diameter, secant, secant line, tangent, congruent circles, concentric circles, and intersecting circles. A secant line intersects the circle in two points. A tangent is a line that intersects the circle at one point. WebOA = OX since both of these are equal to the radius of the circle. The triangle AOX is therefore isosceles and so ∠OXA = a. Similarly, ∠OXB = b. Since the angles in a triangle add up to 180, we know that ∠XOA = 180 - 2a. Similarly, ∠BOX = 180 - 2b. Since the angles around a point add up to 360, we have that ∠AOB = 360 - ∠XOA - ∠BOX.
