What is the difference between a line and a line segment?

A line continues on forever while a line segment has two end points (only a "Segment" of an entire line).

100

What is an angle? How do we measure them?

An angle is a figure created by two rays or two line segments, connected at a common vertex. 

They are measured in degrees by using a protractor

If two lines intersect, and are not perpendicular, they create Vertical Angles.

What can we conclude about them?

The vertical angles opposite each other have equal measurements. 

100

What are the characteristics of a triangle

3 sides, angles, and vertices

100

What is a quadrilateral?

Any 4 sided polygon

200

Define "Ray"

A ray has one endpoint and extends forever in one direction.


200

An acute angle has a measure....

less than 90 degrees

200

When two lines intersect and create a right angle they are...

perpendicular


200

The interior angles of a triangle add up to...

180 degrees


200

How is a rectangle different from a square? How are they the same?

A square has all right angles, equal sides, and opposite sides are parallel.

A rectangle has all right angles, opposite sides are parallel, and opposite sides are equal but not all 4 are equal 

300

How many endpoints does a "line" have?

None! It extends infinitely

300

An obtuse angle has a measure...

more than 90 degrees

300

Two angles that add up to 180 are....

Two angles that add up to 90 are...

Supplementary

Complementary

300

A triangle with no equal sides is called...

scalene

What is it called when an angle is more than 180 but less than 360?

Reflex Angle

400

Describe alternate interior angles or draw a diagram

Teacher will judge

A triangle with all 3 equal sides also has all equal angles. 

True or False

True

400

Name the quadrilateral that has all equal sides but does not have right angles.

rhombus

500

What does it mean if two points are collinear? 

The points are on the same line

500
Define a straight angle.

Creates a straight line, 180 degrees

500

Describe corresponding angles or draw a picture

Corresponding angles have equal measurements and occupy the same relative position

500

Define right triangle, obtuse triangle, and acute triangle. 

right triangle = has one right angle

obtuse triangle = has one obtuse angle

acute triangle = has all acute angles
