Бодлого 1. (Бодолттой)<br />

ASB is a quarter circle. PQRS is a rectangle with sides PQ = 8 and PS = 6. What is the length<br />

of the arc AQB ?<br />

Solution:<br />

Arc AQB is one quarter the perimeter of the circle (because angle S is a right angle).<br />

To find the radius we need to see that the diagonal SQ of the rectangle= radius.<br />

Now use Pythagoras to find the diagonal; 82 + 62 = r2<br />

So r = 10 (You could have spotted that this is a 3-4-5 triangle and so saved this part of the<br />

calculation) The length of the arc = ¼ 20 π = 5π

Which of the following describes the relationship between A and B as shown in the pairs of<br />

numbers in the table below?<br />

Solution:<br />

You can try out the relationships using at least two pairs from the table to see whether the<br />

relationship holds. But it is relatively easy to spot that the first number squared + 1 gives the<br />

second number in each case. So correct answer is B = A² + 1<br />

Бодлого 3. (Бодолттой)<br />

Which of the following pairs of angles must be equal?<br />

Solution:<br />

This question is testing that you know that the angle between a tangent to a circle and a chord<br />

(angle c is such an angle) is equal to the angle in the opposite segment (angle d is in the<br />

segment opposite to c in this case). Similarly, angle a is equal to angle e for the same reason.<br />

So correct answer is B /a and e, and c and d only/
