# Quadrilaterals

Figure \(ABCD\) is a parallelogram with \(\lvert{\overline{AB}} \rvert =7\) and \(\lvert{\overline{AD}}\rvert=10.\) If the points \(E,F,G\) and \(H\) are intersections between the angular bisectors of the four internal angles of the the parallelogram, what type of quadrilateral is \( EFGH\)?

**Note:** The above diagram is not drawn to scale.

\(ABCD\) is a parallelogram and point \(M\) is the midpoint of side \(\overline{AD}\) where \[\lvert{\overline{AB}}\rvert=10, \lvert{\overline{AD}}\rvert=12.\] If \(\lvert{\overline{BM}}\rvert=\lvert{\overline{CM}}\rvert,\) what type of quadrilateral is \(ABCD\)?

In the above diagram, points \(E\) and \(F\) are the feet of perpendiculars drawn from vertex \(A\) of parallelogram \(ABCD\) to sides \(\overline{BC}\) and \(\overline{CD},\) respectively. If \[\lvert{\overline{AE}}\rvert=\lvert{\overline{AF}}\rvert=13,\] what type of quadrilateral is \(ABCD\)?
