Solve Reflex Angle Problems

Introduction to reflex angles tutoring:

Reflex angles are special kind of angles in geometry.  Reflex angle is an angle which measure larger than 180 degree and smaller than 360 degree.  That is it lies between the two values180 degree and 360 degree. In this article we are going to explain about how to solve reference angle problems?

Brief Summary about Reflex Angles

Definition of Reflex angle:

Reflex angle is the angle between the two degrees 180 to 360.

Pictorial representation of a reflex angle:



Here ABC is a reflex angle.  Its measurement is equal to ∠ ABC= 315 degree it also represented as ∠ B = 315 degree.  Here B is called as the edge of an angle.  That is also known as vertex and then the rays AB and BC are represented as the arms of an angle.Please express your views of this topic 4th grade math problems and answers by commenting on blog.

Problems on Solve Reflex Angles

Problem 1:

Identify the following reflex angle and solve which angle is the reflex angle

a)       43 degree

b)       165 degree

c)       220 degree

d)       54 degree

Solution:

The answer is option C. 220 degree is a reflex angle. Because it is lies between the two degrees 180 to 360 degree.  So this is a reflex angle from the pair of angles.

Problem 2:

Identify the following reflex angle and solve which angle is the reflex angle

a)       171 degree

b)       310 degree

c)       55 degree

d)       101 degree

Solution:

The answer is option B. 310 degree is a reflex angle. Because it is lies between the two degrees 180 to 360 degree.  So this is a reflex angle from the pair of angles.

Problem 3:

Identify the following reflex angle and solve which angle is the reflex angle

a)       288 degree

b)       53degree

c)       169 degree

d)       16 degree

Solution:

The answer is option A. 288 degree is a reflex angle. Because it is lies between the two degrees 180 to 360 degree.  So this is a reflex angle from the pair of angles.
