When a line intersects two or more lines the angles formed at the intersection points create special angle pairs. Angle bisector A ray that begins at the vertex of an angle and divides the angle into two angles of equal measure Segment bisector A ray, line or segment that divides a segment into two parts of equal measure Legs of an isosceles triangle The sides of equal measure in an isosceles triangle Base of an isosceles triangle Use the proper symbols for lines, segments, rays, distances, angles, and angle measures. Once we understand what a line is and what an angle is, we can easily use the simple mathematical formulas to determine the length of a line and the area of a parallelogram. The reasons can be given information, definitions, postulates of geometry, or rules of algebra. 3-3, Solving Parallel Line Problems: Video, Notes, Worksheet 3-4a, Proof of Vertical Angles Theorem: Video , Notes , Worksheet , Properties of Congruence , Things to Use as Reasons in a Proof PRACTICE: Triangle Proofs Worksheet Part 2.
