About This Set
These 25 questions are at real Tier 1 level and use SSC's own style of wording. Circles take the biggest share, as they do in the exam: parallel chords, the common chord of two circles, the alternate segment theorem, the tangent and secant rule, and the two kinds of common tangent. The rest cover the orthocentre and circumcentre angles, the inradius from three sides, the altitude on the hypotenuse, the area left after a parallel cut and polygons. Expect wrong options built from the usual mix-ups, such as the full chord used where half is needed, or the direct and transverse tangent formulas swapped. Allow about 25 minutes and try every question before reading any explanation. With 20 or more right, go on to Practice Set 3.
