The process of copying an angle through construction involve ensuring
that the distance between the two rays forming the angle is the same or
equal in the original and copy of the angle at a given equal distance from
the vertex of both angles
The step where the error occur is step 4. She measured the incorrect length
The reason for the above selection is as follows:
The steps to copy an angle are as follows;
- Draw the initial line, <em>l</em>, (the working line) of the copy of the angle as a ray with an endpoint, D
- In the given angle ∠ABC, with the compass placed at point B, construct an arc that intersect the two sides of the given line (BA at point E, and BC at point F) by opening the compass to a radius,<em> r</em>
- Place the compass at the point D on the line <em>l</em> and with the radius r from above, draw an arc (D, r) that intersects the line <em>l </em>at the point G
- Place the compass at point E on line AB, and construct an arc passing through point F, therefore having radial length EF
- Place the compass at point G and construct an arc with radial length EF that intersects the arc (D, r) at point H and draw a ray from the point D passing through point H to complete the construction
A critical step in the copying process involves the finding the distance
between the initial line and the terminal line EF at a given distance DG =
AE from the angle vertex
The step where the error occur is in step 4. by opening the compass
between points A and E which are points on the same line and placing the
compass at point <em>G</em> on line <em>l</em> to draw an arc intersecting the arc created
from point <em>D</em> at <em>H</em>, thereby making the radial distance between the two lines
forming the angle, in the copied angle at a distance E from the vertex,
equal to AE rather than EF
Therefore, the error occurred in step 4. She measured the incorrect length
