Answer: Vertical Angles
Explanation:
AI-generated answer
The relationship between angles a and d can be explained as vertical angles. Vertical angles are formed when two lines intersect. In this case, lines JK and JM intersect at point J, creating four angles: angle B, angle D, angle C, and angle A.
Vertical angles are opposite each other and have equal measures. So, angle a and angle d are vertical angles, meaning they have the same measure.
To visualize this, imagine a "+" sign. Angle a is the top left angle, and angle d is the bottom right angle. These angles are across from each other and have the same measurement.
Therefore, the correct answer is vertical angles.
