Ch 2 Angles Flashcards
What type of angle is AFE

Straight Angle
Are angles BFD and DFE adjacent angles? explain.

Yes, they are adjacent because they share an arm and vertex
Name the angle

Right Angle
I form an angle that is greater than 90º and less than 180º
I’m an obtuse angle
I form an angle that is greater than 180º
I’m a reflex angle
Name the angle

Obtuse Angle
What type of angle or angles is shown

Congruent angle because they are the same angle, meaning the measure is the same. Also vertical angle because angles are opposite of each other, share the same vertex and the two pair of angles add to 360º
134+134=268
46+46= 92
tl= 360
I form an angle that is 90º
I’m a right angle
Name the angle

Acute angle
What type of angles are shown

Supplementary because both angles add up to 180º and adjacent because they share an arm and vertex
I have two or more angles that have the same measure
I’m a congruent angle
Name the angle or angles shown

Complementary because the two angles sum adds to 90º (65+25 = 90) and adjacent because they share the same vertex and arm
What type of angle is CFE?

Right angle
What is an angle?
An angle is a figure formed by two rays that share the same vertex (endpoint)
I share a common side (arm) and a common vertex; what type of angle am I?
I’m an adjacent angle
I form an angle that is exactly 180º
I’m a straight angle
I have two pair of angles that are opposite to each other when two lines intersect. Degrees must add to 360 deg. lastly, I’m always congruent.
I’m a vertical angle
I have two angles whose measures add up to 180º
I’m a supplementary angle
What type of angle is shown?

Congruent angles because they have the same measure
what type of angle is shown?

Reflex angle because it is more than 180º but less than 360º
what type of angle is BFE

Obtuse Angle
I form an angle that is less than 90º
I’m an acute angle
I have two angles whose measures add up to 90º
I’m a complementary angle
