  1. A chord of a circle is subtended by an angle of x degrees. The radius of the circle is 6 √2. What is the length of the minor arc subtended by the chord? We can work this out without a calculator. We can because we know about surds. Diagram not drawn to scale!!

  2. A chord of a circle is the hypotenuse of an isosceles right triangle whose legs are the radii of the circle. The radius of the circle is 6 √2. What is the length of the chord and the minor arc subtended by the chord? Find the chord using Pythagoras and surds and do not evaluate your answer.

  3. A chord of a circle is the hypotenuse of an isosceles right triangle whose legs are the radii of the circle. The radius of the circle is 6 √ 2. What is the length of the chord? (6 √2)2 + (6 √2)2 = chord2 (36 x 2) + (36 x 2) = chord2 Now you can evaluate Chord=√ 144 = 12

  5. A chord of a circle is the hypotenuse of an isosceles right triangle whose legs are the radii of the circle. The radius of the circle is 6 √ 2. What is the length of the minor arc subtended by the chord? Circumference=πD C=2x6 √2π C=12√2π

  6. A chord of a circle is the hypotenuse of an isosceles right triangle whose legs are the radii of the circle. The radius of the circle is 6 √ 2. What is the length of the minor arc subtended by the chord? C=12√2π Minorarc=x12√2π Minorarc=3√2π

  7. A chord of a circle is the side of an equilateral triangle and equal to the radius of the circle. The radius of the circle is 6 √ 2. What is the length of the minor arc subtended by the chord? Remember C=12√2π Diagram not drawn to scale!!
