a b and c are points on the circumference of a circle. XY is a tangent to the circle at the point a. angle bay = 72 ame angle ABC = 54. prove that triangle ABC is an isosceles triangle. you must give a reason for any statement that you make or any calculation that you carry out.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
