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 and on)

Question 2

arc

Answer 2

part of a circle that represents an angle between two 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. Name angles by names of points.

Question 4

perpendicular

Answer 4

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

Question 5

right angles

Answer 5

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

Question 6

intersection

Answer 6

when lines cross they cross at a point called an intersection.

Question 7

acute angles

Answer 7

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

Question 8

obtuse angle

Answer 8

angles greater than a right angle, greater than 90*

Question 9

straight angle

Answer 9

straight line- two rays pointing in opposite directions.

Question 10

complementary

Answer 10

two angles that form a right angle are called complementary angles (90*)

Question 11

supplementary

Answer 11

two angles combines to make a straight angle (180*)

Question 12

vertex

Answer 12

point where two rays meet

Question 13

congruent

Answer 13

having the same measure

Question 14

degrees

Answer 14

a measurement used to measure angles (small measures) symbol-*

Question 15

protractor

Answer 15

a tool that measures angles
