If two lines are perpendicular, then they meet to form. right angles. Theorem 1.7.1: If two lines meet to form a right angle, then these lines are perpendicular. âif and only ifâ. âiffâ. Theorem 1.7.2: If two angles are complementary to the same angle (or to. congruent angles) then these angles are congruent.
A line segment is a part of a line having two endpoints. A ray is a part of a line with one endpoint and goes on and on in one direction... Parallel lines are lines that never intersect or cross one another. Perpendicular lines cross each other or intersect at right angles. An angle is two lines that meet at an endpoint called a vertex. An angle can be named by the three letters that form it or by the letter that is at its vertex. An acute angle is one that measures less than 90 degrees with a protractor - that is how much the angle is open or the lines diverge from the vertex.
