Бодлого 2. (Бодолттой)<br />
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/
