Answer:
Bisecting an angle ⇒ answer a
Step-by-step explanation:
* <em>Lets revise the steps of bisecting an angle</em>
- <em><u>How to construct a bisector of angle XYZ</u></em>
1. Open the compass to any width, and place its pin at the angle’s
vertex Y and draw an arc cuts the two rays of the angle YX and YZ
at two points M and N respectively
2. Open the compass to another width and place its pin at M and draw
an arc between the two rays YX and YZ
3. Without changing the width of the compass place its pin at N and
draw another arc intersects the arc from M at point Q
4. Join YQ which is the bisector of angle XYZ
* <em>Now lets compare these steps by the steps of the question</em>
∵ The vertex of the angle ABC is A represented by Y
∵ The rays of the angle AC and AB represented by YX and YZ
∵ Points D , E represented by points M , N
∴ The construction is " Bisecting an angle "
