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

👉 Learn how to solve problems with rectangles. A rectangle is a parallelogram with each of the angles a right angle. Some of the properties of rectangles are: each pair of opposite sides are equal, each pair of opposite sides are parallel, all the angles are right angles, the diagonals are equal and bisect each other, etc. Given expressions representing some of the parts of a rectangle, we can evaluate the expressions using our knowledge of the properties of a rectangle. 👏SUBSCRIBE to my channel here: https://www.youtube.com/user/mrbrianm... ❤️Support my channel by becoming a member:    / @brianmclogan   🙋‍♂️Have questions?
