Every angle bisector in a triangle bisects the opposite side perpendicularly.
A 'counterexample' would show an angle bisector in a triangle that DOESN'T
bisect the opposite side perpendicularly.
See my attached drawing of a counterexample.
Both of the triangles that Melanie examined have equal sides on both sides
of the angle bisector. That's the only way that the angle bisector can bisect
the opposite side perpendicularly. Melanie didn't examine enough different
triangles.

Answer:
The formula to find a circle's area π (radius)2 usually expressed as π⋅r2 where r is the radius of a circle. The area of a circle is all the space inside a circle's circumference.
Step-by-step explanation:
Answer:
x=54
Step-by-step explanation:
since the line opposite of x is tangent to the circle, the angle made but the point is 90 degrees, so then you add 90 and 36 and subtract that by 180 to get the other angle.
