Move point b to various locations on the circle, and
measure the angles that are formed.
make a conjecture. what relationship exists between the
radius and tangent?
the angles formed by the intersection of the radius
and tangent are right angles.
the angles formed by the intersection of the radius
and tangent measure 90°.
the tangent is perpendicular to the radius.

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
