The angle subtended by joining points a 3,0 and B 0,-2 to the origin point is
Answers
Answer:
a -3,0
b 0,-2
are the points on origin
Concept: The construction of an angle is a type of geometric shape made by connecting two rays at their termini. Three letters that make up the shape of the angle can alternatively be used to symbolise the angle, with the middle letter indicating the location of the angle (i.e.its vertex). Greek characters such,,, etc. are frequently used to denote angles.
The words for measuring angles are degrees, radians, and gradians.
An Angle is the degree of rotation needed to bring two planes (or lines) into correspondence with one another around their point of junction.
In geometry, there are mainly six different kinds of angles. All angles have the following names and characteristics:
The acute angle ranges from 0° to 90°.
The obtuse angle ranges from 90° to 180°.
Right Angle: The angle that is 90 degrees exactly.
Straight Angle: the angle that is exactly 180 degrees
Reflex Angle: The angle between 180 degrees and 360 degrees that is bigger than 180 degrees.
360-degree full rotation: The full rotation of an angle.
Given: points A (3,0) and B (0,-2) joined to the origin
To find: The angle subtended by joining points a 3,0 and B 0,-2 to the origin point
Solution:
Refer the figure for clear explanation.
It is clear from the figure that the angle subtended by joining points A (3,0) and B (0,-2) to the origin point is 90°.
