Which is true about constructing a bisector of the angle?

a.
the measures of the two angles formed are not congruent.

b.
the lengths of the rays that form the angles are halved.

c.
the length of the crease is congruent to the rays in the angle that is bisected.

d.
the measures of the two angles formed are congruent.

When you bisect something you are cutting it in half. so in the image above when you cut it in half you would be forming 2 angles. Your answer is D. because when you cut in half you are going to have equal sides. Its like taking an 75 degrees and bisecting it and each of the new angles would be 37.5.

The length of AC is calculated by 3^2+4^2=c^2

9+16=25
Then square root it and you get 5.
So AC is 5cm.

Then area is calculated using the formula A=BH1/2

4*3*.5=6 is the area
