Question

1. choose the correct answer.

\\(\overline{df}, \overline{ef}\\), and \\(\overline{de}\\) are midsegments of \\(\triangle abc\\)
\\(be = 3\\,\text{cm}\\)
\\(af = 2\\,\text{cm}\\)

what is \\(\triangle def\\) called?
\\(\bigcirc\\) orthotriangle
\\(\bigcirc\\) midsegment triangle
\\(\bigcirc\\) circumtriangle
\\(\bigcirc\\) intriangle

Explanation:

A midsegment triangle is formed by connecting the midsegments of a triangle. Here, \( \overline{DF} \), \( \overline{EF} \), and \( \overline{DE} \) are midsegments of \( \triangle ABC \), so \( \triangle DEF \) is formed by these midsegments. The other terms (orthotriangle, circumtriangle, intriangle) are not standard terms for a triangle formed by midsegments.

Answer:

midsegment triangle
