How to use the medians of similar triangles to determine the missing length

The video tutorial covers the concept of medians and bisectors in triangles, focusing on their properties and how they relate to similar triangles. The teacher explains the process of calculating ratios and solving problems using cross-multiplication. The session includes a mix of geometry and basic arithmetic, with a brief mention of science topics like friction and Newton's law. The tutorial aims to enhance understanding of geometric properties and problem-solving techniques.

What is the term used to describe a line that divides a side of a triangle into two equal parts?

• Altitude

• Bisector

• Perpendicular

• Tangent

In similar triangles, how do the lengths of the medians compare?

• They are unrelated to the sides

• They are twice the length of the sides

• They are in the same ratio as the sides

• They are always equal

If one median is 6 and another is 12, what is the total length of the triangle's side?

• 18

• 12

• 28

• 24
