Webarc: a curved line that is part of the circumference of a circle chord: a line segment within a circle that touches 2 points on the circle. circumference: the distance around the circle. diameter: the longest distance from one … WebAs angles in a triangle total 180° 180°, angle ABC = 180 - (70+40) = 70° ABC = 180 − (70 + 40) = 70°. 2 Use the appropriate circle theorem to find the subtended angle. As angles in the same segment are equal and AC AC is a chord shared by the points B B and D D within the same segment, the angle ADC ADC = angle ABC = 70° ABC = 70°.
