NettetProve that the line segments joining the middle points of the sides of a triangle divide it into four congruent triangles. Login. Study Materials. NCERT Solutions. NCERT Solutions For Class 12. NCERT ... Q. Prove that the line segments joining the midpoints of the sides of a triangle from four triangles each of which is similar to the original ... NettetSolution. We require two auxiliary points on line : a point so that is between and and a point so that is between and as in the picture below. Lines and are parallel and is a transverse for these parallel lines. Therefore angle is congruent to angle since these are alternate interior angles for a transverse meeting parallel lines.

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length. NettetProve that the line joining the mid-point of any two sides of a triangle is parallel to the third side. Medium View solution > A(3,0,−1),B(2,10,6) and C(1,2,1) are the vertices of a triangle.
