1. the symbol ⊥ is used to show that lines are perpendicular
2. if two lines are parallel to the same line, they are parallel to each other.
3. the symbol || is used to show that lines are
4. parallel lines are lines that never intersect

draw the lines described below.

1. draw parallel lines a and b and transversal c.
2. draw line d perpendicular to line e.
3. draw line f intersecting line g

multiple choice

1. what type of angle is formed by the intersection of two perpendicular lines? a acute b obtuse c right d straight
2. if lines a and b are perpendicular to line c, what word best describes how lines a and b relate to each other? f intersecting g parallel h perpendicular i skew

Explanation:

1. The symbol $\|$ represents parallel lines.
2. Perpendicular lines intersect to form right - angles (90 degrees).
3. If two lines are perpendicular to the same line, they are parallel to each other.

Answer:

1. parallel
2. C. right
3. G. parallel
