The circumference of a circle of radius r is:
सही उत्तर: ख) 2πr
Circumference = 2πr = πd. πr² is the area of the circle.

The perpendicular drawn from the centre of a circle to a chord:
सही उत्तर: ग) Bisects the chord
A perpendicular from the centre divides a chord into two equal parts. Conversely, the line joining the centre to the midpoint of a chord is perpendicular to it.

Inscribed angles standing on the same arc of a circle are:
सही उत्तर: घ) Equal
All angles at the circumference standing on the same arc are equal. The ratio 1:2 relates an inscribed angle to the central angle.

The opposite angles of a cyclic quadrilateral are:
सही उत्तर: क) Supplementary (sum = 180°)
In a cyclic quadrilateral, each pair of opposite angles adds up to 180°. They are equal only in special cases such as a rectangle.

The angle in a semicircle is:
सही उत्तर: ख) 90°
An angle inscribed in a semicircle stands on a diameter, which subtends 180° at the centre. So the inscribed angle is half of that, 90°.

The angle at the centre of a circle is ______ the angle at the circumference standing on the same arc.
सही उत्तर: ख) Twice
The central angle is double the inscribed angle on the same arc. For example, if the inscribed angle is 40°, the central angle is 80°.

A line segment joining any two points on a circle is called a:
सही उत्तर: ग) Chord
A chord joins two points on the circle; the diameter is the longest chord. A tangent touches the circle at only one point.

A quadrilateral with exactly one pair of parallel sides is called a:
सही उत्तर: घ) Trapezium
A trapezium has only one pair of opposite sides parallel. A parallelogram has both pairs of opposite sides parallel.

-
A quadrilateral with all sides equal and all angles 90° is a:
सही उत्तर: क) Square
A square has four equal sides and four right angles. A rhombus has equal sides but its angles need not be 90°.

The area of a triangle and a parallelogram standing on the same base and between the same parallels are related as:
सही उत्तर: क) Area of triangle = ½ × Area of parallelogram
Both have the same base and the same height, and a triangle's area is ½ × base × height. So the triangle is exactly half of the parallelogram.
