Vocabulary	True or False	Formulas	Angle Types	Calculations
100 Semi-Circle What is half a circle called?	100 True if a, b and c are sides of a right angled triangle; a^2 + b^2 = c^2	100 a^2 + b^2 = c^2 What is the Pythagoras Theorem?	100 An Obtuse Angle What is an angle whose measure is greater than 90° and less than 180°?	100 50.4 cm Calculate the circumference of a circle with a 8 cm radius.
200 Tangent What is a line that touches the circle in one point only called?	200 True Equilateral triangles have all three sides equal. Isoceles triangles have two equal sides. Scalene triangles consist of three different side lengths.	200 (n-2) x 180 = total interior angles What is the formula used to find the total interior angles of a polygon?	200 Corresponding Angles What type of angles are created where a transversal crosses other (usually parallel) lines and the angles are the ones at the same location at each intersection?	200 13.1 cm The length of an arc of a circle if the radius is 12.5 cm and the angle at the centre is 60°.
300 Diameter What is any chord passing through the center of a circle called?	300 True The line drawn from the center of a circle at right angles to a chord, bisects the chord.	300 (a:b)^3 If the ratio used for line lengths of two trianlges is a:b what would the ratio for the volume be?	300 A Reflex Angle What is an angle whose measure is greater than 180° and less than 360°?	300 15.9 cm Find the radius of a circle with the circumference 1.
400 Circle What is the set of points that are all equidistant to one point called?	400 True Similiar shapes are equiangular.	400 If a^2 + b^2 = c^2, the triangle is right angled. If the original of a theorem states; If a triangle is right angled, it is a^2 + b^2 = c^2 What would the converse be?	400 Adjacent Angles What type of angles share a common side and a common vertex, but do not overlap?	400 23.9° Find the angle of a sector with area 30 cm^2 and radius 12 cm.
500 Chord What is a line segment joining two parts of a circle called?	500 False If there were four angles; A, B, C and D A and B were supplementary C and D were supplementary A, B, C and D all are on line segment EF All four of the angles would make a complementary angle.	500 A = (θ/360°) × (π r)^2 What is the formula used to calculate the area of a sector?	500 Alternate Exterior Angles What type of angles are created where a transversal crosses two (usually parallel) lines and each pair of these angles are outside the parallel lines, and on opposite sides of the transversal.	500 20.9 cm The second hand of a clock is 10 cm long. How far does the tip of the second hand travel in 20 seconds?
