Question 3

angles

Answer 3

<= angle symbol

Question 4

perpendicular

Answer 4

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

Question 5

right angles

+ the angles that are square =lines that form it are perpendicular and the angle measures 90* *= degrees

Question 6

intersection

Answer 6

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

Question 7

acute angles

Answer 7

Angles that are less than a right angle ; less than 90*

Question 8

obtuse angles

straight line- two rays pointing in opposite directions.

Question 10

complementary (angles)

Answer 10

two angles that form an right angle are called complementary angles.

Question 11
