Bond paper b. Arbitrarily choose a location on the left side of the perpendicular line and push a pin. Designate the position of the pin as point B. Draw a straight line connecting points A and B. c. Position the mirror center at A such that the mirror's surface is parallel to the horizontal line. d. Position yourself on the right hand side of the perpendicular line and locate point C. Put a pin on that location such that the line BA and line AC are perpendicular to each other. e. Using a protractor measure the angle subtended by line AB to the perpendicular line. This will be called the incident angle, 01. f. Using a protractor measure the angle subtended by line AC to the perpendicular line. This will be called the reflection angle, 0- g. Repeat steps 1-6 for five (5) different locations of point B and their corresponding point C. Flat Mirror A Push Pin, Protractor Drawn line B Observer Push Pin
