In a circle when a tangent and radius come to touch, the form a 90° angle. when an angle is inscribed by a semicircle, it forms a 90° angle. In a circle when two inscribed angles intercept the same arc, the angles are congruent. circle, opposite angles are supplementary.

Chapter 1 Basic Geometry Geometry Distance Between Points Distance measures how far apart two things are. The distance between two points can be measured in any number of dimensions, and is defined as the length of the line connecting the two points. Distance is always a positive number. 1-Dimension (line segment)
