Types of Angles
What do you call an angle that measures exactly 90 degrees?
Right angle
What tool is used to measure angles?
Protractor
Lines that are equal distance apart and never intersect are called:
Parallel lines
You are given a straight angle that has been divided into 3 different angles. If one angle is 68 degrees and another angle is 32 degrees, how many degrees does the last angle measure?
80 degrees
True or False: An acute angle has a degree measurement that is greater than a right angle.
False
If you are asked to measure an angle of 45 degrees, how would correctly align the protractor up to the angle?
Place the circle of the protractor on the vertex of the angle and align the protractor up with the base part of the angle.
Lines that intersect to form a right angle are called:
Perpendicular lines
If one angle in a triangle measures 60 degrees and another angle measures 70 degrees, what is the measure of the third angle?
50 degrees
If an angle measures 160 degrees, what type of angle is it?
Obtuse Angle
When measuring angles with a protractor, describe a strategy that could be used to help you decide if you should use the top or bottom scale on the protractor.
Teacher will judge answer.
What is the definition of a line?
Teacher will judge the answer.
All triangles have 3 angles. When added together, what is the sum of all 3 angles in a triangle?
180 degrees
An angle that has a degree measure that is greater than 90 degrees but less than 180 degrees.
Obtuse Angle
Using a protractor, draw an angle that measures 76 degrees.
Teacher will judge the angle.
Draw a picture of a ray.
Teacher will judge the drawing.

282 degrees
What is the total degree measurement of a circle?
360 degrees
Why is it important to measure angles correctly?
Teacher will judge answer.
Name a shape that has two sets of parallel lines.
Teacher will judge answer.
