Question

determining congruent circles. circle a has a radius of 6. which circles are congruent to circle a? choose two correct answers.

Explanation:

Step1: Recall congruent - circles property

Two circles are congruent if they have the same radius.

Step2: Calculate radii of given circles

For circle D, diameter = 12, so radius $r_D=\frac{12}{2}=6$. For circle E, radius $r_E = 6$. For circle H, diameter = 6, so radius $r_H=\frac{6}{2}=3$. For circle F, diameter = 12, so radius $r_F=\frac{12}{2}=6$. For circle G, diameter = 6, so radius $r_G=\frac{6}{2}=3$.

Answer:

circle F, circle E
