Question

In the given diagram, name the point(s)

a) In the interior of $\angle DOE$

(b) In the exterior of $\angle EOF$

(c) On $\angle EOF$

Answer 1

In any plane, figure and angle divides the plane in which it lies into two parts-

1. The part of the plane which is between the two sides of a triangle is called the interior of the angle.
2. The part of the plane which is outside the two sides of angle extended endlessly is called exterior of the angle .

Therefore

(a) Point(s) in the interior of $\angle DOE$ is/are- $A$

(b) Point(s) in the exterior of $\angle EOF$ is/are- $C,A$ and $D$

(c) Point(s) on the $\angle EOF$ is/are- $E,B,O$ and $F$
