Answer:

If BC = 2.6 cm then find 2BD + BC/2 = 6.5cm

Step-by-step explanation:

Given,

         BC = 2.6 cm

    In Δ ACB and Δ ABD

            AC = AD (Given)

           ∠A = ∠D (Given)

            AB = AB (Common)

            Δ ACB ≅  ΔABD ( By SAS congruence )

            BC = BD ( by CPCT)

            2BD + BC/2

            2 × 2.6 + 2.6/2

           =   5.2 + 1.3

           =   6.5 cm

hence proved  2BD + BC/2 = 6.5 cm

The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangle. The centroid of the triangle separates the median in the ratio of 2: 1. It can be found by taking the average of x- coordinate points and y-coordinate points of all the vertices of the triangle.

Centroid Theorem

The centroid theorem states that the centroid of the triangle is at 2/3 of the distance from the vertex to the mid-point of the sides.

Centroid Theorem

Suppose PQR is a triangle having a centroid V. S, T and U are the midpoints of the sides of the triangle PQ, QR and PR, respectively. Hence as per the theorem;

QV = 2/3 QU, PV = 2/3 PT and RV = 2/3 RS

Centroid of A Right Angle Triangle

The centroid of a right angle triangle is the point of intersection of three medians, drawn from the vertices of the triangle to the midpoint of the opposite sides.

Centroid of a Square

The point where the diagonals of the square intersect each other is the centroid of the square. As we all know, the square has all its sides equal. Hence it is easy to locate the centroid in it. See the below figure, where O is the centroid of the square.
