We have been given that PQ bisects . In the second statement of the given two-column proof, the statement is
.
This implies that the two angles formed by bisection of angle by the line PQ are equal. We know that the reason for this is simple. It is the definition of bisection of an angle that the two smaller angles formed will be equal to each other.
Therefore, the reason for statement 2 of the given two column proof is c) Definition of bisect
Answer:
P(x, y) = (√3/2, -1/2)
Step-by-step explanation:
There are a few special angles whose trig functions are worthwhile to remember. The top half of the table in the second attachment shows these.
The first attachment shows a unit circle and coordinates of the points at these special angles. It is worthwhile to remember there are 2π radians in a circle, so -π/6 radians (your angle) corresponds to a positive angle of 11π/6 radians.
__
The coordinates of P are ...
P(x, y) = (√3/2, -1/2)
_____
<em>Additional comment</em>
The coordinates of any point at angle α on a unit circle are ...
(x, y) = (cos(α), sin(α))
