Using the properties of a rectangle to find the missing value of an angle

The video tutorial covers the properties of rectangles, focusing on angles and diagonals. It explains that opposite sides are congruent and parallel, and that diagonals are congruent but do not bisect angles. The tutorial also discusses how consecutive angles are supplementary and all angles in a rectangle are 90 degrees. The instructor solves an equation to find the measure of specific angles, emphasizing the importance of understanding different types of angles in rectangles.
