This video introduces the idea of using the Pythagorean Theorem in isosceles triangles. Isosceles triangles have two equal side lengths and two equal angles while the Pythagorean Theorem relates the sides lengths in a right triangle.
The general strategy for these example problems is to notice that the vertical line in the triangles splits the isosceles triangle into two congruent right triangles by the ASA (Angle Side Angle) congruence relation. Focusing on one of the right triangles, an equation can be set up between the side lengths using the Pythagorean Theorem to find the missing length.
