13) Using only the given information for each problem, determine whether \(\overline{DM}\) is a perpendicular bisector, angle bisector, median and/or altitude of \(\triangle RST\).
a) \(\overline{OM}\cong\overline{ME}\) b) \(\angle 1\) is a right angle c) \(\overline{DM}\perp\overline{OE}\) and \(\overline{DO}\cong\overline{DE}\) d) \(M\) is equidistant from \(\overrightarrow{DO}\) and \(\overrightarrow{DE}\). |
16) Is Mary closer to the Grocery store or the Book store? How about Jack? Explain your reasoning.
17) Is the salt truck closer to Route \(50\) or to Interstate \(90\)? How about the warehouse? Explain your reasoning.
20) Draw a diagram of \(\triangle AXY\) where \(\overleftrightarrow{AB}\) is a perpendicular bisector of \(\overline{XY}\), \(\overleftrightarrow{AB}\) bisects \(\angle A\), \(\overline{AB}\) is a median of \(\triangle AXY\), and \(\overline{AB}\) is an altitude of \(\triangle AXY\). Label all possible parts of the diagram.
