Geometry: Measurement of Angles (Level 9 of 9)

This video is the final installment in the Measurement of Angles series. It covers two examples that require algebra to solve angle measurement problems. The first example involves a right angle and uses algebraic expressions to find the measure of angle POC. The second example involves solving a system of equations to find the values of x and y for angles TRS and XRS. The video concludes the series and introduces the next topic, collinearity.
