Question

Accepted Answer

# Brief Explanations:
1. Recall the definitions: In a right triangle, the hypotenuse is the side opposite the right angle (the longest side). For an acute angle (like ∠J), the adjacent side is the one that forms the angle with the hypotenuse, and the opposite side is the one not forming the angle.
2. In right triangle JKM, the right angle is at M. So side $a$ (JK) is the hypotenuse (opposite the right angle at M). For ∠J:
   - Side $b$ (JM) is adjacent to ∠J (forms ∠J with hypotenuse $a$).
   - Side $c$ (KM) is opposite to ∠J (does not form ∠J with hypotenuse $a$). Wait, no—wait, let's re - check. Wait, ∠J is at vertex J. So the sides:
     - Hypotenuse: The side opposite the right angle (angle M) is JK, which is $a$. So $a$ is hypotenuse.
     - For ∠J: The adjacent side is the one that is part of ∠J and is not the hypotenuse. ∠J is between sides $b$ (JM) and $a$ (JK), so $b$ is adjacent. The side opposite ∠J is $c$ (KM), because it's across from ∠J. So the first option says "a is the hypotenuse, b is adjacent, c is opposite"—wait, no, wait the options: Wait the first option is "a is the hypotenuse, b is adjacent, c is opposite". Wait let's re - analyze:
     - Hypotenuse: In right triangle, hypotenuse is the side opposite the right angle. Right angle at M, so hypotenuse is JK ($a$). Correct.
     - Adjacent to ∠J: The side that is next to ∠J and is not the hypotenuse. ∠J is at J, between sides JM ($b$) and JK ($a$). So JM ($b$) is adjacent to ∠J.
     - Opposite to ∠J: The side that is across from ∠J, which is KM ($c$). So the first option "a is the hypotenuse, b is adjacent, c is opposite" is correct? Wait no, wait the second option: "a is the hypotenuse, b is opposite, c is adjacent"—no, let's draw the triangle. Vertex J, K, M with right angle at M. So:
       - ∠J: sides:
         - Hypotenuse: JK ($a$) – correct.
         - Adjacent: JM ($b$) – because it's one of the two sides forming ∠J (the other is hypotenuse $a$).
         - Opposite: KM ($c$) – because it's not forming ∠J, it's opposite. So the first option: "a is the hypotenuse, b is adjacent, c is opposite" is correct? Wait the first option is "a is the hypotenuse, b is adjacent, c is opposite" – yes. Wait but let's check the options again:
       - Option 1: a is hypotenuse, b adjacent, c opposite.
       - Option 2: a hypotenuse, b opposite, c adjacent.
       - Option 3: a adjacent, b opposite, c hypotenuse – no, $a$ is hypotenuse, so this is wrong.
       - Option 4: a opposite, b hypotenuse, c adjacent – wrong, $a$ is hypotenuse.
       Wait, maybe I made a mistake. Let's use the standard definitions:
       - Hypotenuse: The side opposite the right angle. Right angle at M, so hypotenuse is JK ($a$) – correct.
       - For angle J:
         - Adjacent side: The side that is part of angle J and is not the hypotenuse. Angle J is between JM ($b$) and JK ($a$), so JM ($b$) is adjacent.
         - Opposite side: The side that is not part of angle J and is opposite to it. That is KM ($c$). So the first option: "a is the hypotenuse, b is adjacent, c is opposite" is correct. Wait but let's check the options again. Wait the first option is "a is the hypotenuse, b is adjacent, c is opposite" – yes. Wait no, wait the problem's options: Wait the first option: "a is the hypotenuse, b is adjacent, c is opposite"—yes, that matches our analysis. Wait but maybe I mixed up opposite and adjacent. Wait, no—let's take angle J. The sides:
         - Hypotenuse: $a$ (JK) – correct.
         - Adjacent to ∠J: the side that is adjacent (next to) ∠J, which is $b$ (JM) because ∠J is at J, between $b$ (JM) and $a$ (JK).
         - Opposite to ∠J: the side that is across from ∠J, which is $c$ (KM). So the first option is correct. Wait but let's check the second option: "a is the hypotenuse, b is opposite, c is adjacent"—no, $b$ is adjacent, not opposite. So the first option is correct.
