At timestamp 2:00 how do we know that the larger triangle is 2 times the area of the small triangle?

The three triangles shown are similar since they have the same angles, and this is because of the properties of parallel lines cut by other lines (called transversals).The larger triangle has a height of \(44,\) while the smaller triangle has a height of \(22,\) and that tells us that the larger triangle is twice the size of the smaller triangle.
