Extracted text: 3. By Similar Triangles C Distance AC=4.2m Distance BC=8.88m Distance Cb=? Distance Ca=2.29m OBS A Distance AB=? Given: A line through AB an obstruction. Required: To find the distance AB by similar triangle. Procedure: 1. Select a convenient point C, and measure AC and BC. 2. Set point a conveniently along AC and measure Ca. 3. Solve for Cb from: Cb : aC = BC : AC 4. Locate point b along BC by laying the computed distance Cb from C. 5. Measure ab. Solve for AB from: AB : AC = ab : Ca
