Geometry: Measurement of Angles (Level 7 of 9)

The video tutorial covers challenging examples involving congruent angles and algebraic expressions. It begins with solving a problem involving a right angle and the measurement of angle RAT. The second example involves finding the measure of angle A by solving for x in congruent angles. The final example demonstrates using algebra to find the measurement of angle 1 in a right angle problem. The video emphasizes setting up geometric relations before using algebra to solve problems.
