Question

find the error based on the figure shown, laura says that \\( \frac{1}{3} ap = ad \\). kareem disagrees. is either of them correct? explain your reasoning.

Explanation:

Brief Explanations

In a triangle, the centroid (point \( P \)) divides each median into a ratio of \( 2:1 \), with the longer segment being from the vertex to the centroid. Here, \( AD \) is a median (since \( D \) is the midpoint of \( CE \), as indicated by the tick marks on \( CB \) and \( CE \), implying \( B \) and \( D \) are midpoints, so \( AD \) is a median). So, \( AP:PD = 2:1 \), meaning \( AP=\frac{2}{3}AD \), or \( \frac{3}{2}AP = AD \), not \( \frac{3}{4}AP = AD \). Thus, Kareem is correct because Laura's statement misapplies the centroid ratio.

Answer:

Kareem is correct. The centroid \( P \) divides median \( AD \) such that \( AP:PD = 2:1 \), so \( AP=\frac{2}{3}AD \) (or \( \frac{3}{2}AP = AD \)), not \( \frac{3}{4}AP = AD \).
