Question 2

arc

Answer 2

part of a circle that repeats an angle between two intersecting lines.

Question 3

angles

Answer 3

When lines intersect they form angles and are the spaces or shapes that are formed between the intersecting lines - they meet at a vertex. Named 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

lines that form it are perpendicular and the measures of 90.

Question 6

intersection

Answer 6

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

Question 7

acute angles

Answer 7

Angles are less than a right angle; greater than 90.

Question 8

obtuse angles

Answer 8

Angles that are greater than a right angle; greater than 90.

Question 9

straight angles

Answer 9

straight line - two rays pointing in opposite directions.

Question 10

complementary angles

Answer 10

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

Question 11

Supplementary angles

Answer 11

two angles combined to form a straight angle (180).

Question 12

vertex

Answer 12

the point where two rays meet.

Question 13
