MDP N C What is NC if NP = 18? 9 MC bisects NP…so 18/2 If DP = 7.5, find MP. 7.5 + 7.5 = 15
AE B C D If CD = 2x + 5, BD = 4x – 1, SOLVE FOR X. BD = CD 4x - 1 = 2x + 5 2x = 6 x = 3
The intersection of the medians is called the CENTRIOD. How many medians does a triangle have?
When 3 or more lines (or rays or segments) intersect in the same point, they are called concurrent lines (or rays or segments). The point of intersection of lines is called the point of concurrency.
Point of Concurrency of the Medians Always INSIDE the triangle.
Theorem The length of the segment from the vertex to the centroid is twice the length of the segment from the centroid to the midpoint.
