Measuring Angles - Part 4 |
||||||||||||

Think of a whole pie as 360°, if you eat a quarter (1/4) of it the measure would be 90°. If you ate 1/2 of the pie? Well, as stated above, 180° is half, or you can add 90° and 90° - the two pieces you ate! If you cut the whole pie into 8 equal pieces. What angle would one piece of the pie make? To answer this question, you can divide 360° by 8 Usually, when measuring an angle, you will use a protractor, each unit of measure on a protractor is a degree °.
Try a few best guesses, the angles below are approximately 10°, 50° , 150°,
1. = approximately 150° 2. = approximately 50° 3 = approximately 10° Part 5: Bisectors, Congruencies and Theorems |
