The median of a triangle is the line that connects a vertex of the triangle to the midpoint of the side opposite to the vertex. The medians intersect at a point called the centroid of the circle and divide the median in the ...
Two shapes are said to be similar if the ratio of corresponding side lengths is fixed. Congruent shapes are also similar shapes as the ratio of side lengths is 1. Answer and Explanation:1 If two triangles are similar, then the ratio of side le...
