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 quadrilateral with all sides equal and all angles 90° is a:
सही उत्तर: क) Square

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.

The diagonals of a parallelogram:
सही उत्तर: ख) Bisect each other
In every parallelogram, the diagonals bisect each other. They are equal only in rectangles and perpendicular only in rhombuses and squares.

Which of the following is NOT a valid condition for congruency of triangles?
सही उत्तर: ग) A.A.A.
If all three angles are equal, the triangles are similar but may differ in size, so A.A.A. does not prove congruency. S.S.S., S.A.S., A.S.A. and R.H.S. are valid conditions.

A triangle whose three sides are all different in length is called:
सही उत्तर: घ) Scalene triangle
A scalene triangle has all sides (and all angles) different. An isosceles triangle has at least two equal sides.

Which of the following sets is a Pythagorean triple?
सही उत्तर: घ) 5, 12, 13
5² + 12² = 25 + 144 = 169 = 13², so they satisfy Pythagoras' theorem. The other sets do not, e.g. 6² + 8² = 100, not 121.
