Question

DEFINITION OF RIGHT ANGLE STRAIGHT ANGLE AND COMPLETE ANGLE

Answer 1

Answer:

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

In Maths, a straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line. Basically, as per angles definition in maths, when two rays are joined end to end, they form an angle.

A full angle, also called a complete angle, round angle, or perigon, is an angle equal to radians. corresponding to the central angle of an entire circle. Four right angles or two straight angles equal one full angle. SEE ALSO: Acute Angle, Angle, Central Angle, Obtuse Angle, Reflex Angle, Right Angle, Straight Angle.

Answer 2

Answer:

Right angle : Angle which is equal to 90° is known as right angle.

Straight angle: Angle made in a straight line i.e the angle measures 180° is known as straight angle.

Complete angle: The angle which measures 360° is known as Complete angle.
