... Two intersecting lines form four angles. If one of those angles is 90◦ , then by symmetry each of the other angles must be 90◦ . Drawing perpendicular lines is harder than recognizing them because it requires motor skills. Hands-on activities drawing perpendicular lines deepen students’ understandin ...

... equals the desired angle. If you subtract this angle from the value of a right angle, the number that remains is the second acute angle. (e) Using the table of sines in figure 2, find the two acute angles in a right triangle ABC if AB=20, AC=12 and BC=16. Since the sine table only lists sines for in ...
