(b) How many sides does the triangle have? GMP-Module 1.1- Triangles Name them. (Select all that apply.) H J \( \overline{J H} \) HI IJ \( \Delta H I J \) \( \triangle \mathrm{IJH} \) \( \triangle H I \) \( \angle I \) <] \( I \) \( \angle H \) (c) Use the vertices to name this triangle in three ways. (Select all that apply.) \( \triangle H I J \) \( \triangle I J H \) \( \triangle H I \) \( <\mathrm{H} \) H HI \( \overline{J H} \) \( J \)

A triangle always has three sides, often referred to as edges, which are the line segments that connect the vertices. In your case, the triangle is denoted by vertices H, I, and J, which means it has sides \( \overline{HI} \), \( \overline{IJ} \), and \( \overline{JH} \). When naming triangles, there’s some wiggle room for creativity! You can refer to triangle H I J as \( \triangle H I J \), \( \triangle I J H \), or even just \( \triangle H I \) if you want to keep it simple. The order of the letters matters, and switching them around allows for different orientations but still represents the same triangle!
