An angle is a fraction of a circle where the whole circle is 360°. A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor. Two angles with the same measure are called congruent angles. Congruent angles are denoted as Sum is a see also of total. Total is a synonym of sum. As nouns the difference between total and sum is that total is an amount obtained by the addition of smaller amounts while sum is a quantity obtained by addition or aggregation or sum can be the basic unit of money in kyrgyzstan. pc_11.4_practice_solutions.pdf: File Size: 509 kb: Download File.
