90° called?
Please answer I will mark you brainliest​

Answer 1

Answer:

1. A reflex angle is an angle which is more than 180 degrees and less than 360 degrees. For example, 270 degrees is a reflex angle. In geometry, there are different types of angles such as acute, obtuse and right angle, which are under 180 degrees. The least number of 30° angle you could need to make reflex angle is six 30° angles.
2. Right angle: It is one-quarter of a whole turn and is the same as the angle made by a horizontal line and vertical line. The measure of the angle is 90º. Some examples are shown below: Acute angles: The angles that lie between 0º and 90º are called acute.
3. Angles that are 90 degrees (θ = 90°) are right angles. • Angles that are 180 degrees (θ = 180°) are known as straight angles. • Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles.

Answer 2

1. least number of 30 degree angle need to make a reflex angle = 7

because 7*30 =210 which is more than 180

2. quarter of a complete angle =

complete angle/4

3. angle measuring 90 degree is right angle
