Answer 1

Circle A has center of (2, 3), and a radius of 5 and circle B has a center of (1, 4), and a radius of 10. What steps will help show that circle A is similar to circle B?

Dilate circle A by a scale factor of 2. *****
Translate circle A using the rule (x + 1, y − 1).
Rotate circle A 180° about the center.
Reflect circle A over the y-axis.


Which of the following could be used to calculate the area of the sector in the circle shown above?

π(5in)30 over 360
π(5in)230 over 360*****
π(30in)25 over 360
π(30in)5 over 360

Circle A is shown with a central angle marked 30 degrees and the radius marked 5 inches.



A circle is centered at (−3, 2) and has a radius of 2. Which of the following is the equation for this circle?

(x + 3)2 + (y − 2)2 = 2
(x − 3)2 + (y + 2)2 = 4
(x + 3)2 + (y − 2)2 = 4*****
(x − 3)2 + (y + 2)2 = 2

Which of the following is a step in constructing a circle inscribed in a triangle?

Use a compass to locate the intersection of the midpoint of each side.
Use the perpendicular bisectors to find the center of the circle.*****
Use a compass to locate the intersection of the altitude of each side.
Use the angle bisectors to find the center of the circle.



Quadrilateral OPQR is inscribed in circle N, as shown below. Which of the following could be used to calculate the measure of ∠OPQ?

Circle N is shown with a quadrilateral OPQR inscribed inside it. Angle O is labeled x plus 16. Angle P is not labeled. Angle Q is labeled 6x minus 4. Angle R is labeled 2x plus 16.

m∠OPQ + (2x + 16)° = 180°
m∠OPQ = (6x − 4)° + (2x + 16)°
m∠OPQ + (x + 16)° + (6x − 4)°= 360°
m∠OPQ = (x + 16)° + (6x − 4)°*****




Alex drew a circle with right triangle PRQ inscribed in it, as shown below:

The figure shows a circle with points P, Q, and R on it forming an inscribed triangle. Side PQ is a chord through the center and angle R is a right angle. Arc QR measures 80 degrees.

If the measure of arc QR is 80°, what is the measure of angle PQR?

50°
40°
80°******
70°
