100
Lines that never touch
What are parallel lines?
100
An angle whose measure is less than 90 degrees.
What is an acute angle?
100

two angles whose sum is 90*.

What are complementary angle?

100
a 3 sided closed figure
What is a triangle?
100
The sum of the interior angles of a triangle
What is 180 degrees?
200
lines that cross.
What are intersecting lines?
200

an angle whose measure is greater than 90 degrees and less than 180 degrees

What is an obtuse angle?

200

when 2 parallel lines are cut by a transveral, these angles are in the same relative location and they are equal, sometimes called "F" angles

What are corresponding angles?

200

the missing measure of a triangle that has a right angle, and a 45* angle.

What is 45*?

200
The sum of the interior angles of a 4 sided figure
What is 36o degrees
300
Lines that intersect to form right angles.
What are perpendicular lines?
300
an angle whose measure is equal to 180 degrees
What is a straight angle?
300

when 2 parallel lines are cut by a transveral, these angles are outside the parallel lines and on opposite sides of the transversal and they are equal, sometimes called "S" angles which are very similar to a backward "Z" angle

What are alternative exterior angles?

300

the measure of all 3 angles of an equilateral triangle

What is a 60*?

300

Mr. McGeachy will give you a piece of paper to answer the question.

What is 55*

400
A lines that intersects two other lines.
What is a transversal?
400

An angle that measures between 180* and 360*

What is a reflex angle?

400
two angles whose sum of their measures equals 180 degrees
What are supplementary angles?
400
the measure of the 4th angle if a 4 sided shape already has three 90* angles in it

What is a 90*

400

Mr. McGeachy will give you a sheet of paper to answer this question...

B is equal to  30*

500

The letter that represents the vertices in angle XYZ 

What is Y?

500
an angle whose measure is equal to 90 degrees
What is a right angle?
500

when 2 parallel lines are cut by a transveral, these angles are inside the parallel lines and on opposite sides of the transversal and they are equal, often called "Z" angles

What are alternate interior angles?

500

a triangle has two obtuse angles and one acute angle (T-F)

It is false

500

Mr. McGeachy will give you a piece of paper

Angle B measures 135*
