Question

Olivia attempted to construct a circle circumscribed about a triangle, but the circle only passed through one of the three vertices of the triangle.
What logically could have gone wrong?

A. The compass involuntarily changed the radius setting when drawing circle.
B. Only 2 perpendicular bisectors were constructed instead of 3.
C. The altitudes were constructed incorrectly.
D. The lines representing the angle bisectors were not extended enough.

Answer 1

When constructing a circle circumscribing about a triangle, we bisect any two lines and not angles. 
It is not necessary to bisect the three sides.
The most logical mistake the learner could have made are:
A. The compass involuntarily changed the radius setting when drawing circle and 
C. The altitudes were constructed incorrectly.
