Which of the following describes the relationship between A and B as shown in the pairs of
numbers in the table below?
Solution:
You can try out the relationships using at least two pairs from the table to see whether the
relationship holds. But it is relatively easy to spot that the first number squared + 1 gives the
second number in each case. So correct answer is B = A² + 1
Бодлого 3. (Бодолттой)
Which of the following pairs of angles must be equal?
Solution:
This question is testing that you know that the angle between a tangent to a circle and a chord
(angle c is such an angle) is equal to the angle in the opposite segment (angle d is in the
segment opposite to c in this case). Similarly, angle a is equal to angle e for the same reason.
So correct answer is B /a and e, and c and d only/
