100
What is the characteristics of an obtuse angle
It is an angle that is larger than 90 degrees and smaller 180 degrees.
100
Can an obtuse angle be apart of a complimentary angle? Explain your answer.
No, because an obtuse angle is more than 90 degrees whereas complimentary angles add up to 90 degrees.
100
Can an acute angle be apart of supplementary angles? Explain why/why not.
Yes because acute angles are less than 90 degrees and supplementary angles add up to 180 degrees.
100
What do angles around a point add up to?
360 degrees
100
Name three objects around the room that are/have right angles.
e.g. Corner of tables, corner of windows, corner of books, corner of laptops, etc. (Teacher will decide if your answer is valid)
200
Which angle is equivalent to a full circle?
A revolution angle.
200
Explain what is a complimentary angle?
Different angles that make up/add up to 90 degrees.
200
Explain what is a supplementary angle?
Angles that add up to/make up 180 degrees.
200
What are angles around a point?
Angles that add up to/make up 360 degrees and form a revolution.
200
Name three objects around the room that is an acute angle.
Stapler openings, pair of open scissors, clock arrows, etc. (Teacher will decide if your answer is valid)
300
Name the three types of angles that have a unchangeable degree.
Right angles, straight angles and revolutions
300
How many degrees is the missing angle?
`
30 degrees
300
Which two angles that have the same degree make up a supplementary angle?
Two right angles. (90 degrees each)
300
Find the missing angle.
The missing angle is 160 degrees.
300
Name three objects around the room that is a straight angle.
E.g. Rulers, side of tables, side of door, side of windows, side of books, side of walls and floors. (Teacher will decide if your answer is valid)
400
Name all 6 types of angles.
Acute, Right Angle, Obtuse, Reflex, Straight Angle and Revolution.
400
How many degree's is X?
17 degrees
400
What degrees is Y?
103 degrees
400
Can one straight angle and two right angles placed together be considered as angles around the point? Explain why/why not.
Yes. A straight angle is 180 degrees and right angles are 90 degrees. Angles around a point add up to 360 degrees.
180 + 90 + 90 = 360
400
Which shape has angles that always add up to 180 degrees?
Triangles.

On a rectangle, how many degrees do it's sides add up to?
360 degrees because it has four right angles.
90 degrees X 4 = 360
