Determine the missing lengths of a 45 45 90 triangle ex 1

This video tutorial explains how to find missing sides in a 45-45-90 special right triangle. It covers identifying the hypotenuse and calculating its length by multiplying a known leg by the square root of 2. The tutorial emphasizes that the legs of a 45-45-90 triangle are equal, simplifying the process of finding missing sides.

What type of triangle is discussed in the text?
