given:  ,  , and  
 
If two segments from the same exterior points are tangent to a circle, then they are congruent. Since   and  are segments from the same exterior point ( ), then
 
  and  
 
 Since   and   are segments from the same exterior point ( ), then

Question 9
 
If   and  , calculate the value of  .
 
circle   with tangent line segment   touching at point ; line segment  
 
If a line is tangent to a circle, then it is perpendicular to the radius, making   a right triangle. 
Since you have to calculate  , use the Pythagorean Theorem. 
 
  
  
  
  
  
 
 
 
Question 10 
If  ,  , and  , calculate the values of line segment   and line segment   
image of a circle inscribed inside triangle  ; the points of intersection points are: on side   point  , on side   point  , and on side   point  
 
Tangents to a circle from the same point are the same length, so 
 
   
 
     
and,

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  .
 
now from the second step we get a perpendicular bisector of line   at point  .
 
This means that   ( since bisector means that the line is cut into two equal parts)
 
Hence, option:   is correct.
