angle

Everyday

1. An angle is the space or turn between two lines that meet at a point; it is measured in degrees. tree →
2. An angle is a corner, or the direction from which you look at something: «from this angle». tree →
3. An angle is a way of thinking about a problem or story: «Look at it from a different angle.» tree →
4. To angle something is to point it slightly sideways; to angle is also to fish with a rod and line. tree →

In the lessons

In maths, angles are measured with a protractor: a right angle is 90°, an acute angle is less than 90°, an obtuse angle is between 90° and 180°, a straight angle is 180°, and a full turn is 360°. Angles in a triangle add up to 180°, and in a four-sided shape to 360°. In everyday life you angle a mirror or a lamp; in sport you angle a shot. Phrases: «right angle», «at an angle», «from every angle», «angle for» (try to get something without asking directly).

Examples

• A square has four right angles. tree →
• Measure the angle with a protractor. tree →
• The angles in a triangle add up to 180 degrees. tree →
• An acute angle is smaller than a right angle. tree →
• The picture is hanging at an angle. tree →
• From this angle the house looks huge. tree →
• Try looking at the problem from another angle. tree →
• He angled the mirror so he could see the road. tree →
• Not long afterwards the two sisters went to angle in the brook, meaning to catch fish for dinner. tree →

Note

Countable. Do not mix with «angel» (a spirit with wings): angLE vs angEL. Maths traps: the size of an angle does not depend on how long its lines (arms) are; 90° is a quarter turn. Angles on a straight line add to 180°; angles around a point add to 360°.

In Jewish tradition

Here it means a corner or a side of a doorframe, and also a fishhook on a line used for catching fish. In the primary lessons: In maths, angles are measured with a protractor: a right angle is 90°, an acute angle is less than 90°, an obtuse angle is between 90° and 180°, a straight angle is 180°, and a full turn is 360°.

Examples

• And for the entrance of the Sanctuary he made doors of olive-wood, the door-posts within the frame having five angles. (Prophets 1KI.6.31, JPS 1917) tree →
• The fishers also shall lament, and all they that cast angle into the Nile shall mourn, and they that spread nets upon the waters shall languish. (Prophets ISA.19.8, JPS 1917) tree →
• They take up all of them with the angle, they catch them in their net, and gather them in their drag; therefore they rejoice and exult. (Prophets HAB.1.15, JPS 1917) tree →
