perpendicular lines skew lines parallel lines intersecting lines If two lines lie in the same plane and DO NOT intersect, they are called The first step to copying angle A to make angle B is to copy the ray. make a new ray somewhere else on the paper. swing equal setting arcs from points A and B. swing different setting arcs from points A and B. copy the ray. make a new ray somewhere else on the paper. swing equal setting arc from point B. swing different setting arc from point B. The next step to copying angle A to make angle B is to copy the ray. Open the compass with one end on point C and one on point D Open the compass with one end on point C and one on point A swing a same setting arc from point E intersecting the arc The next step to copying angle A to make angle B is to C D E copy the ray. Open the compass with one end on point C and one on point D Open the compass with one end on point C and one on point A swing a same setting arc from point E intersecting the arc After opening the compass to measure the distance from point D to point C... C D E dilate cut in half copy rotate To bisect means to To bisect ABC the first step would be to swing an arc from point B swing an arc from point A swing an arc from point C create a new ray swing a same setting arc from point E intersecting the arc After opening the compass to measure the distance from point D to point C and copying this measurement at point E to the arc and marking an arc... Draw a ray from point B to the intersection of the arcs Open the compass with one end on point C and one on point D Open the compass with one end on point C and one on point A C D E To create a line perpendicular to AB through point C, first create a line segment on AB to bisect by swinging an arc from point A swinging an arc from point B swinging an arc from point C draw line segments to connect points A, B, and C To create a line perpendicular to AB through point C, first create a line segment on AB to bisect by swinging an arc from point C as below. Then...swing equal setting arcs from points A and B swing equal setting arcs from points D and E swinging an arc from point C draw line segments to connect points A, B, and C To create a line perpendicular to AB through point C, the only step left in the drawing below is to Swing equal setting arcs from points A and B connect points A, B, and C swinging an arc from point C draw a line where the second and third arcs intersect Copying an angle to create alternate interior, alternate exterior, or corresponding angles will create a midpoint a perpendicular bisector perpendicular lines parallel lines Opening a compass to place an end on each of two points will measure the length of the segment between the points to allow us to easily copy this segment elsewhere on the paper bisect this segment copy an angle construct parallel lines Constructing perpendicular lines is based on bisecting a line segment bisecting an angle copying a line copying an angle a ray an angle a line a midpoint What is created when a line segment is folded in half so that endpoints touch? A B perpendicular lines skew lines parallel lines intersecting lines If two lines intersect at right angles, they are called a line parallel to AB a line perpendicular to AB a regular triangle a regular quadrilateral A line is drawn connecting points A and C. This would be the first step in constructing ↔ ↔ a line parallel to AB a line perpendicular to AB a regular triangle a regular quadrilateral Swinging an arc from point C across line AB would be the first step in constructing ↔ ↔ Swinging an equal setting arc from the top (or bottom) of a circle as the below picture is the first step to constructing a regular quadrilateral perpendicular bisector midpoint regular triangle Swinging an arc from both endpoints of a diameter of a circle to just the other side of the midpoint as below is the beginning to creating a regular quadrilateral set of parallel lines midpoint regular triangle |
