WebThe measure of an angle formed by a 2 secants drawn from a point outside the circle is half the the difference of the intercepted arcs: In the picture below, the measure of ∠ x is 1 2 the difference of the arcs intercepted by the two secants. Remember that this theorem only makes use of the intercepted arcs. Web2. We can pretend to measure the circumference of a circle by saying circumference = π * diameter. Since π itself is an approximation, a "measurement" of the circumference will always and forever be just an approximation and NEVER an exact number. It is quite interesting because one can clearly see a circle has bounds unlike a straight line ...

WebWhat is the measure of ∠BOA and ∠AOE in the circle shown below? Solution Since BE is a straight line (diameter of the circle) then, ∠BOA + AOE = 180° (x + 50) ° + (x + 10) ° = 180° 2x + 60°= 180° Subtract 60° on both sides. 2x = 120° By dividing both side by 2, we get x = 60° Now substitute.
