Question

3. Circle C is shown below with exterior point P.(a) Construct the two tangents from point P to circle C.Label the points of tangency A and B. Leave allconstruction marks.с(b) Draw in AB.(c) Explain why triangle PAB must be an isosceles triangle.

Answer 1

Triangle PAB is isosceles because the distance from point P to A is congruent with the distance from point P to B. But the length of side AB is diferent, so this triangle has 2 sides with the same length and one with a different length so this is an isosceles triangle.
