What is the measure of this arc (use a protractor to calculate this)? What is the measure of the inscribed angle (use protractor)? How are the measures you found in 5 and 6 related? Make a conjecture about the relationship between a central angle and an inscribed angle that intercept the same arc. Part C: You are now going to test your conjecture.

Navy ships use cross bearings instead of sextant angles in hazardous waters. Unlike other large ships, the Navy ships must take a fix every three minutes. War Ships (especial atomic) are big news for grounding. ... You jump to the sextant and three armed protractor! “Your protractor is broken” you jump to something to get that important fix ...

Ask leading questions to assess student understanding of what an angle is, the types of angles, estimating the measure of an angle, and the use of the protractor to draw and measure angles. Now let’s examine some angle pairs. If the sum of the measures of two angles is 90º, then the angles are complementary angles.

The protractor is one of the most poorly understood measuring instruments found in schools. Part of the difficulty is the units (degrees) are so small. It would be physically impossible to cut out a single degree and use it to measure an angle like in the previous activity. Another difficulty is there are no visible angles showing on a protractor.
