Angle vocabulary

Question 1

Parallel

Answer 1

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

Question 2

Arc

Answer 2

Part of a circle that represents the 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.

Question 5

right angles

Answer 5

lines that form it are perpendicular and the angles measure 90 degrees

Question 6

intersection

Answer 6

when lines cross they cross at a point called the intersection

Question 7

acute angles

Answer 7

angles that are less than a right angle; grater than 90%

Question 8

obtuse angles

Answer 8

angles greater than a right angle; greater than 90%

Question 9

straight angle

Answer 9

a straight line- two rays pointing in the opposite directions and it equals 180 degrees.

Question 10

complementary angles

Answer 10

two angles that form a right angle are called complementary angles
= 90 degrees

Question 11

supplementary angles

Answer 11

two angles to combine a form a straight angle= 180 degrees

Question 12

vertex

Answer 12

the point where two rays meet

Question 13

congruent

Answer 13

having the same measurment

Question 14

degrees

Answer 14

a measurement used to measure angles

Question 15

protacter

Answer 15
