Given:
is the angle bisector of
.
To find:
The measure of .
Solution:
It is given that is the angle bisector of
. It means
...(i)
Now,
[Using (i)]
Divide both sides by 2.
Therefore, the required value is .
The list attached shows the coordinate of (x, y) after transformation when reflecting over x, y-axis, and lines y = x, y = -x
<h3>What is geometric transformation?</h3>It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have two lines of reflection:
y = x and
y = -x
The point is (x, y)
After reflecting over line y = x the coordinate (x, y) becomes:
(y, x)
After reflecting over the line y = -x the coordinate (x, y) becomes:
(-y, -x)
Thus, the list attached shows the coordinate of (x, y) after transformation when reflecting over x, y-axis, and lines y = x, y = -x
