1.In triangle ABC, AB = 13 cm, AC = 9 cm and angle ABC = 35°. Given that angle ACB is obtuse, work out its size. Give your answer to 1 decimal place.
(a)23.4°
(b)124.1°
(c)89.1°
(d)55.9°
2.AB is a diameter of a circle with centre O, and C is a point on the circle. A student writes four statements to prove that angle ACB = 90°. Statement 1: OA = OC, since both are radii, so triangle OAC is isosceles with angle OAC = angle OCA. Statement 2: OB = OC, since both are radii, so triangle OBC is isosceles with angle OBC = angle OCB. Statement 3: in triangle ABC, the three angles sum to 360°, so angle OAC + angle OBC + angle ACB = 360°, meaning 2 × angle ACB = 360° and angle ACB = 180°. Statement 4: A, O and B lie on a straight line, since AB is a diameter through the centre O. Which one of these four statements is mathematically incorrect?
(a)Statement 4 — A, O and B lie on a straight line
(b)Statement 3 — a triangle's angles are said to sum to 360°
(c)Statement 1 — OA = OC because both are radii
(d)Statement 2 — OB = OC because both are radii
3.A quadrilateral has exactly two lines of symmetry, its two pairs of opposite angles are equal, and its diagonals are not equal in length. Write down the name of this quadrilateral.
(a)Parallelogram
(b)Rhombus
(c)Square
(d)Kite
4.A line joins the points A(0, 0, 0) and B(9, 12, 8) in a three-dimensional coordinate system in which the z-axis is vertical. Work out the angle this line makes with the horizontal (the xy-plane). Give your answer correct to 1 decimal place.
(a)28.1°
(b)41.6°
(c)61.9°
(d)33.7°
5.The point R(−6, 9) is translated by the vector $(- 11 5)$ . Write down the coordinates of the image of R.
(a)(−1, 9)
(b)(−1, −2)
(c)(−6, −2)
(d)(−11, 20)
6.A ship's radio can be heard up to 30 km from the ship. A lighthouse's light can be seen up to 20 km from the lighthouse. The ship and the lighthouse are 40 km apart along the coast. Describe the region where BOTH the radio can be heard AND the light can be seen.
(a)the lens-shaped region where the two circles overlap
(b)the whole smaller circle, since it fits inside the larger one
(c)no overlap — 30 km and 20 km don't add to 40 km
(d)a straight strip, exactly halfway between the two
7.Which of the following is the correct definition of a regular polygon?
(a)All of its sides are equal in length
(b)It has at least one line of symmetry
(c)Equal sides and equal interior angles
(d)All of its interior angles are equal
8.A solid ball has a radius of 7 cm. Work out the surface area of the ball. Use π = 3.14.
(a)615.44 cm²
(b)1436.03 cm³
(c)153.86 cm²
(d)87.92 cm²
9.A crane's hook starts at the point (3.4, 9.5) on a construction site plan measured in metres. It moves along the vector $(- 4.5 - 1.2)$ to pick up a beam, then along the vector $(- 2.5 0.8)$ to place it. Work out the single column vector that describes the hook's overall movement from its start position to where it places the beam.
(a) $(- 2 - 2)$
(b) $(- 7 - 0.4)$
(c) $(7 - 0.4)$
(d) $(- 7 2)$
10.An enlargement has a scale factor of −2. Priti says the image must be a mirror image of the original shape. Is Priti correct?
(a)No — it's a 180° rotation, not a reflection.
(b)Yes — negative numbers always mean a reflection.
(c)Yes — upside down is the same thing as mirrored.
(d)No — negative factors change size, not orientation.
11.A conservatory has a roof panel shaped like a regular octagon. Work out the interior angle of the octagon, then use it to work out the size of the reflex angle at the same vertex, on the outside of the roof panel.
(a)225
(b)45
(c)315
(d)135
12.Every diameter of a circle is an example of a more general type of straight line joining two points on the circle. Which term names that more general type of line?
(a)arc
(b)tangent
(c)chord
(d)radius
13.A chocolate bar is a prism. Its cross-section is a triangle with a base of 6 cm and a perpendicular height of 5 cm, and the bar is 12 cm long. Work out the volume of the bar.
(a)180 cm³
(b)66 cm³
(c)15 cm³
(d)360 cm³
14.From an external point P, two tangents PA and PB touch a circle with centre O at A and B. Angle AOB = 112°. Work out the size of angle APB.
(a)68°
(b)112°
(c)90°
(d)56°
15.A ferris wheel's circular frame has centre O. A support strut runs from O to a point A on the rim, and a second strut runs from O to point B on the rim, with angle AOB = 76°. A cabin is mounted at point C on the major arc AB, and D is a separate point on the minor arc AB. Work out the difference between angle ACB and angle ADB.
(a)104°
(b)38°
(c)180°
(d)142°
