The length of AP is 14 units
Step-by-step explanation:
The centroid point of a triangle is:
- The point of intersection of the three medians of the triangle
- The centroid point divides each median into two segments at a ratio 2 : 1 from its vertex
- The length of the segment from the vertex to the centroid is
of the length of the median
- The length of the segment from the centroid to the base is
of the length of the median
Look to the attached figure
In Δ ABC
∵ D is the mid-point of AB
∵ E is the mid-point of BC
∵ F is the mid-point of AC
∵ AE , BF and CD are the medians of the triangle
∵ AE , BF and CD are intersected at P
∴ P is the centroid of the triangle
- By using the rule above
∴ AP = AE
∵ AE = 21 units
∴ AP = × 21
∴ AP = 14 units
The length of AP is 14 units
