3 Hint) Construct the line segments from the center of the circle to the ends of the chord.
Figure posted below at 3rd post.
1)In the figure above the measure of angle AME is x degrees, then the measure of angle EMB is 180-x degrees.
My answer is 1267200 inches
I don't know why I think this is the answer?I know a straight line is 180 degrees. This is a line adjacent to it.
2) If a central angle is 30 degrees, then the arc it defines is also 30 degrees.
My answer is Properties of a central angle. Because an arc is equal to central angle.
3) If a radius bisects a chord, then the lengths of the parts of the radius on either side of the chord are equal.
This proof is the definition of a radius. But why?
4) If a circle has a central point M, and both point A and point D are on the circle, then ls_MA and ls_MD will be equal.
This is a false proof. Therefore, unfounded?
5) The given points (4, -8), (4, -5), and (-2, -6) make a right triangle
This is also false proof. Does not make a right triangle. Making it an unfounded statement.
Please explain to me more on these subjects. Thanks.
