Angle bisector of angleA of triangleABC is perpendicular to BC prove it is isosceles?
Let D represent the point on BC where the bisector of A intersects BC. Because AD bisects angle A, angle BAD is congruent to CAD. Because AD is perpendicular to BC, angle ADB is congruent to ADC (both are right angles). The line segment is congruent to itself. By angle-side-angle (ASA), we know that triangle ADB is congruent to triangle ADC. Therefore line segment AB is congruent to AC, so triangle ABC is isosceles.

The question is based on a complete misunderstanding of what a polygon is. A plane figure is not necessarily a polygon. The following are some examples of plane figures which are not polygons:a straight linea curvean anglea circlean ellipsea parabola.
How do you find the unknown side of a right triangle?
Use Pythagoras's equationa^2 + b^2 = c^2where c is the hypotenuse - the longest side which is opposite the right anglea and b are the two smaller legs.So, if the two legs are known and the hypotenuse is unknown:square the two known sides;add the numbers togethertake the square root.This is the measure of the hypotenuse. Suppose the hypotenuse and one side is known, the other is unkown:square the two known sides;subtract the smaller answer from the larger;take the square root.This is the measure of the missing leg.
