The endpoints of ef are e(xe , ye) and f(xf , yf). what are the coordinates of the midpoint of ef? (xf2,yf2) (xe2,ye2) (xe+xf2,ye+yf2) (xe+xf2,ye+yf2)

The answer is option A.

Use a compass to draw a circle of any radius less than ,with vertex B as the center.

Step-by-step explanation:

Steps for drawing angle bisector of ∠ ABC.

Step 1. Draw any angle ABC

Step 2. Draw a circle using compass of any radius less than AB, with vertex B as the center. Then the arc will cut on AB an BC such that say point P on AB and point Q on BC.

Step 3. Now take measure more than AP or BQ

Step 4. Cut the arcs using compass on point P and point Q. You will get the intersection point.

Step 5. From that point say S draw a line to B. You will have SB, that is the angle bisector of angle ABC
