The tangent-tangent angle is formed by two tangents drawn from a point outside a circle to points on the circle. To find the measure of the tangent-tangent angle, you take half the difference of the intercepted arcs. In this case, the arcs measure 135 degrees and 225 degrees. Therefore, the measure of the tangent-tangent angle is (\frac{1}{2} (225^\circ - 135^\circ) = \frac{1}{2} (90^\circ) = 45^\circ).

True. The measure of a tangent-tangent angle is indeed half the difference of the measures of the intercepted arcs. This theorem applies to angles formed outside a circle by two tangents that intersect at a point, providing a relationship between the angle and the arcs it intercepts.

In a circle, the measure of an angle formed by a chord and a tangent at a point on the circle is half the measure of the intercepted arc. Since segment DC is a diameter, angle DAB is an inscribed angle that intercepts arc DB. Therefore, the measure of arc DB is twice the measure of angle DAB, which is 68 degrees. Since arc BC is the remainder of the circle, arc BC measures 360 degrees - 68 degrees = 292 degrees.
It is 90 degrees between the circle's diameter and its tangent
