To solve the problem step by step, we will analyze the triangle \( \Delta PQR \) where \( D \) is the midpoint of \( \overline{QR} \). ### Step 1: Identify the properties of \( PM \) Since \( D \) is the midpoint of \( \overline{QR} \), we can conclude that \( PM \) is perpendicular to \( QR \). This means that \( PM \) acts as the height (or altitude) from point \( P \) to line \( QR \). **Hint:** Remember that the altitude of a triangle is a line segment from a vertex perpendicular to the opposite side. ### Step 2: Identify the properties of \( PD \) ...
