Angles

Question 1

parallel

Answer 1

lines that will never cross and are the same distance apart and may go on forever (will not cross if they go on & on)

Question 2

arc

Answer 2

part of a circle that represents an angle between 2 intersecting lines

Question 3

angles

Answer 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

Question 4

perpendicular

Answer 4

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

Question 5

right angles

Answer 5

lines that form it are perpendicular and the angle measures 90*

Question 6

intersection

Answer 6

when lines cross at a point-called an intersection

Question 7

acute angles

Answer 7

angles that are less than a right angle, less than 90*

Question 8

obtuse angles

Answer 8

angles greater than a right angle, greater than 90*

Question 9

straight angle

Answer 9

straight line-2 rays pointing in opposite directions

Question 10

complementary angles

Answer 10

2 angles that form a right angle are called complementary angles

Question 11

supplementary angles

Answer 11

two angles combine to form a straight angle

Question 12

vertex

Answer 12

the point where 2 rays meet

Question 13

congruent

Answer 13

having the same measure

Question 14

degrees

Answer 14

a measurement used to measure angles (small amount)

Question 15

protractor

Answer 15

a tool that measures angles
