Welcome to your Chapter 13 (Practical Geometry - Circles)
How many common tangents can be drawn for two intersecting circles?
How many common tangents can be drawn for two disjoint circles?
The portion of a circle between two radii and an arc is called:
A line intersecting a circle is called:
If the two circles touches externally, then the distance between their centre is equal to the:
The length of the diameter of a circle is how many times the radius of the circle?
The circumference of a circle is a called:
Tangents drawn at the end points of the diameter of a circle are:
The measure of the external angle of a regular hexagon is:
The measure of the external angle of a regular octagon is:
The lengths of two transverse tangents to pair of circles are:
If two circles touch each other, their centre and point of contact are:
The tangent and radius of the circle at the point of contact are:
Tangent is a line touching a circle at:
How many common tangents can be drawn for two touching circles?
If the distance between the centre of two circles is equal to the sum of their radii, then the circles will:
Circles having three points in common
How many tangents can be drawn from a point outside the circle?
The circle which touches the three sides of a triangle is called:
Angle inscribed in a semi-circle is:
If the in-centre and circum-cenrtre of a triangle coincide, the triangle is:
