Kinds of angles” формируется компетенция ОПК-5: обладает обладать способностью к подготовке и редактированию текстов профессионального и социально значимого содержания. В рамках формирования компетенции у студентов вырабатываются следующие умения, навыки: Уметь понимать информацию текстов из учебной литературы в соответствии с конкретной целью; выступать с подготовленным сообщением. Владеть навыками оформления речевых высказываний в соответствии с грамматическими и лексическими нормами устной и письменной речи, фонетическими нормами (устная речь) и основными правилами орфографии и пунктуации (письменная речь) иностранного языка, не допуская ошибок, препятствующих речевому общению; навыком использования двуязычных словарей при чтении различного типа текстов; профессиональными основами речевой. коммуникации с использованием терминологии данной дисциплины. При работе над текстом применяются интерактивные технологии: работа малыми группами, решение ситуационных задач. ANGLES An angle is formed when two straight lines meet at a point. The lines are called the sides of an angle. The point at which they meet is called the vertex of the angle. The unit of measure used in measuring an angle is the degree. If a pair of "dividers", or compasses, be opened an angle is formed, and the more they are opened, the greater is the angle. The size of an angle does not depend upon the length of the arms, but upon the extent to which they are opened. An angle is usually denoted, in geometry, either by one capital letter at the vertex, or by three capitals, one at the vertex and one on each arm. When three letters are used, that at the vertex must be read or written between the other two. KINDS OF ANGLES Right angle. If one side of an angle turns a quarter of a complete circle away from the other side, the angle that is formed is a right angle. It contains 90. Complementary angle. When two angles put together form a right angle, and thus their sum is 90°, the angles are complementary. Straight angle. If one side of an angle turns half a complete circle away from the other side, the angle that is formed is a straight angle. The sides of a straight angle lie in the same straight line. The number of degrees in a straight angle is 180°. Acute angle. If one side of an angle turns less than a quarter of a circle away from the other side, the angle formed is an acute angle. It is, therefore, smaller than a right angle, or less than 90°. Obtuse angle. If one side of an angle turns more than a quarter of a circle but less than half a circle away from the other side, the angle formed is obtuse angle. It is greater than a right angle but smaller than a straight angle. It contains more than 90 but less than 180°. Reflex Angle. If one side of an angle turns more than half a circle (180°) but less than a complete (360°) away from the other side, the angle formed is a reflex angle. A reflex angle is greater than a straight angle.
