given: AB+=+5.5, CD+=+7, and FE+=+19.5
If two segments from the same exterior points are tangent to a circle, then they are congruent. Since AF and AB+are segments from the same exterior point (A), then
+AB+=+AF+ and AF+=+5.5
Since CB and CD are segments from the same exterior point (B), then
CD+=+CB and CB+=+7
Since EF and ED are segments from the same exterior point (E), then
FE+=+DE and DE=+19.5
AE+=+AF+%2B+FE
AE+=+5.5+%2B+19.5
AE+=+25
CE+=+CD+%2B+DE
CE+=+7+%2B+19.5
CE+=+26.5
Therefore,
AE+=+25 and CE+=+26.5

Question 9
If BD+=+2.4 and AB+=+1.0, calculate the value of DA.
circle D with tangent line segment AC touching at point+B; line segment AD
If a line is tangent to a circle, then it is perpendicular to the radius, making ABD a right triangle.
Since you have to calculate DA, use the Pythagorean Theorem.
%28AB%29%5E2%2B+%28BD%29%5E2=+%28AD%29%5E2
%281.0%29%5E2%2B+%282.4%29%5E2=+%28AD%29%5E2
1%2B+5.76=+%28AD%29%5E2
6.76=+%28AD%29%5E2
AD=sqrt%286.76%29
AD=2.6

Question 10
If AB+=+9, CD+=+12, and FE+=+22, calculate the values of line segment AE and line segment CE
image of a circle inscribed inside triangle ACE; the points of intersection points are: on side AC point B, on side AE point F, and on side CE point D
Tangents to a circle from the same point are the same length, so
  FA+=+AB+=+9
  AE+=+FA+%2BFE+=+9+%2B22+=+31
and,
  DE+=+FE+=+22
  CE+=+CD+%2BDE+=+12+%2B22+=+34
The side lengths are
AE+=+31, CE+=+34

Question 11
What is true about the construction of a regular hexagon inscribed in a circle?


answer:
The circle intersects each vertex of the hexagon.

Question 12.
Which of the following shows a circle passing through three non-collinear points, A, B, and C?

One and only one circle can be drawn through A, B, and C
answer: circle circumscribed about triangle

Question 13
Which of the following is true about the following construction of a tangent to a circle from a point outside of the circle?


Since the construction of the tangent of a circle from a point outside the circle is given by the following steps:
Draw a line connecting the point to the center of the circle.
 Construct the perpendicular bisector of that line.
Place the compass on the midpoint, adjust its length to reach the end point, and draw an arc across the circle .
Where the arc crosses the circle will be the tangent points.
Hence from the first step we get a line segment OB.
now from the second step we get a perpendicular bisector of line OB at point M.
This means that OM=MB ( since bisector means that the line is cut into two equal parts)
Hence, option: B is correct.
answer: OM=MB
