By1.2 – Use Segments and Congruence. Geometry Ms. Rinaldi. Postulate. In Geometry, a rule that is accepted without proof is called a postulate or axiom . Postulate 1 – The Ruler Postulate. Measure the length of ST to the nearest tenth of a centimeter.

ByMeasure the length of ST to the nearest tenth of a centimeter. Align one mark of a metric ruler with S . Then estimate the coordinate of T . For example, if you align S with 2 , T appears to align with 5.4 . ST = 5.4 – 2 = 3.4. The length of ST is about 3.4 centimeters. ANSWER.
