Answer:
Circle A and circle D are congruent ⇒ 3rd answer
Explanation:
* Lets talk about the circle
- Any circle has diameter
- Any circle has radius which is half the diameter in length
- All the circles are similar because the measure of all circles is 360°
and there is the ratio between the radii
- The two circles are congruent if they have the same radii because
the congruence is special case of similarity when the ratio equal 1
* Lets look to the figure to solve the problem
- There are four circles in the figure
# Circle A with radius 3"
# Circle B with radius 4"
# Circle C with radius 5"
# Circle D with radius 3"
∵ The radius of circle A = 3"
∵ The radius of circle D = 3"
∴ The radii of circle A and circle D are congruent
∴ Circle A and circle D are congruent
