The picture shows lines that cross inside a snowflake. The lines form 6 equal-size angles. The total measure of the 6 angles is 360°.
What is the measure of the angle marked with a question mark?
A.
60°
B.
90°
C.
300°
D.
360°
Since the total measure of the 6 angles is 360°, and they are all equal in size, each angle must be 360° divided by 6, which equals 60°.
Therefore, the measure of the angle marked with a question mark is 60°.
Answer: A. 60°
