angle vocabulary

Question 1

Answer 1

parallel

Question 2

part of a circle that represents an angle between two intersecting lines

Answer 2

arc

Question 3

• When lines intersect they form angles and angles are the spaces or shapes that are formed between the intersecting lines- they meet at a vertex. Name angles by names of points

Answer 3

angles

Question 4

lines that form square corners when they intersect, they form right angles

Answer 4

perpendicular
