The intersecting secants theorem says
That is, for either secant line, you take the length of the part of the secant line outside the circle (6 and 5 in this case) and multiply it by the "total" length of the secant line between the point where the two secant lines intersect and the furthest point where the secant touches the circle (6+12=18 and 5+x in this case). The theorem says these products are equal.
Both angle measures and segment lengths.
An angle is a shape formed by two rays that meets at a point. The angle is measured by degrees. The angle is formed by the sides of an angle which shares the common endpoint called the vertex. The line is horizontal stretch with a vertical line PQ. It will measure the angle and segments lengths.
Intersecting chords theorem:
i.e. when two chords intersect, the products of the resulting line segments' lengths are equal. Then
The correct option is;
(Choice C) Both angle measures and segment lengths
The given transformations are;
The reflection over the line, , with, A rotation about the point P. Another reflection over . A rotation about the point Q, we have;
The transformations involve changes only in the orientation and location of the pre-image, which remain rigid, therefore, there are no changes in the segment lengths or angle dimensions
Therefore, the correct option is, both angle measures and segment lengths.
