description of the line in relation to the circle shown with center
O?    
a.  Radius  c.  Chord  b.  Diameter  d.  Secant 


2.

Given the circles shown with centers
M and N, which line would represent a common external tangent?
   


3.

Which of the arcs listed below
represents a MAJOR ARC?
(You may assume YW and ZX
are diameters)

5.

Is there enough evidence to suggest that triangle below is a right
triangle?
(Figure may not be drawn to
scale.)
a.  Yes; Triangle ABC is a right triangle.  b.  No; Triangle ABC is a NOT right
triangle. 


6.

right triangle?
a.  5 cm, 5 cm, 7 cm  b.  3 cm, 2 cm, 13
cm  c.  11 cm, 60 cm, 61 cm 


7.

Based on the measures provided in
the diagram, determine if is tangent to the circle with center
C.
(Figure may not be drawn to scale.)
   
a.  Yes; is tangent because triangle ABC is a right
triangle with the right angle at  b.  No; is tangent
because triangle ABC is a NOT a right triangle. 


8.

Based on the measures provided in
the diagram, determine the measure of .
