Lines

• Parallel - two lines running in the same direction - they will NEVER cross

• Not Parallel - two lines that will cross at some point

Lines

• Perpendicular lines always intersect at right angles, which are 90^o

• If lines cross, but not at right angles, they are NOT perpendicular

Multiple Select

Select all that are true.

• Parallel lines never intersect.

• Parallel lines intersect at a right angle.

• Perpendicular lines never intersect.

• Perpendicular lines intersect at a right angle.

Multiple Choice

if two lines never meet each other

• parallel lines

• intersecting lines

• line segment

• none

Multiple Choice

In the given figure ,these lines are

• perpendicular lines

• parallel lines

• intersecting lines

• none

Multiple Choice

Perpendicular lines have the same slope.

• True
• False

Multiple Choice

Parallel lines have the same slope

• True
• False

Angles

• Acute angle - less than 90^o

• Right angle - equal to 90^o; right angles are perfect corners

• Obtuse angle - greater than 90^o, but less than 180^o

• Straight angle - equal to 180^o, which is a perfectly straight line

Naming Angles

The vertex (point) letter is always the MIDDLE of the name. The first letter is the start of the line/ray and the last letter is the line/ray where you end up

This angle is <ABC
