Line Segments, Points, Lines, Planes, Angles, Rays (easy stuff)

Question 1

A _______is straight, has 2 endpoints and is a piece of a line

Answer 1

Segment

Question 2

What are the two ways to name a segment?

Answer 2

Segment AB (Segment BA) the segment symbol over top of TWO Capital letters

Question 3

A ______is a flat surface; has no thickness, extends infinitely in all directions, and is names using 3 non-collinear points

Answer 3

Plane

Question 4

What is this symbol: ≈

Answer 4

Congrunecy sign…no need to yell cuz

Question 5

What is an adjacent angle?

Answer 5

An angle with a common vertex/side

Question 6

Length of a Segment

Answer 6

The absolute value of the diff. between coordinates.

2 wyas to write this.. mAB(w/ line overtop) or AB

AB(with line overtop) is only a name not a mesure

Question 7

Define Coplanar

Answer 7

All points are said to be coplanar if a single plane contains them all. (them being points)

Question 8

Non-colinear

Answer 8

If the points do not lie on the same line

Question 9

A ______represents a location, and has no thickness

Answer 9

Point

Question 10

Intersect

Answer 10

When geometric figures have one or more points in common, they are said to intersect.

Question 11

A _____has one endpoint and a direction. A _____ is a piece of a line.

Answer 11

Ray

Question 12

Whats a supplementary angle?

Answer 12

Two angles that add up to 180 degrees

Question 13

What is Segment Congruence?

Answer 13

If 2 segments are the same length they’re congruent. Two ways to write this shown below.

AB≈ XY is called an Equality Statement

Question 14

Whats a complementary angle?

Answer 14

Two angles that add up to be 90 degrees

Question 15

Non- Coplanar

Answer 15

A point(s) that is NOT located on the plane

(you dont need a picture for this, cuz)

Question 16

Define Colinear

Answer 16

Points are said to be colinear if a straight line can contain them all.

Question 17

What are the two ways to name a line?

Answer 17

Line M AB (you get the idea…)

Question 18

A ____ is Straight and extends infinitely in both directions

Answer 18

Line, cuzo

Question 19

What is a complementary angle?

Answer 19

Two angles that add up to 90 degrees

Question 20

What are the only two things that you can measure in Geometry?

Answer 20

Segment and Angle

Question 21

Whats a linear pair of angles?

Answer 21

A pair of adjacent angles whose noncommon sides are opposite rays. When you put them together they should make a straight line.

Question 22

An _____ is made up of two rays called SIDES. The rays share the same endpoint called a VERTEX. The vertex is the middle used in the name.

Answer 22

Angle

Question 23

Define Endpoints

Answer 23

A point at the end of a segment or the starting point of a ray.

Question 24

What is a supplemantary angle?

Answer 24

Two angles that add up to 180 degrees
