Unit 1 Geometry

Points, Lines, and Planes

100

Explain what collinear points are.

Points that are on the same line

200

Where do two lines intersect?

A point

300

Give me all three ways to name a line.

on board

400

Name both ways you can name a plane.

Explain

500

True or False

A line is made up of two points and has no thickness or width. 

It also extends both directions forever.

True

Segment Addition Postulate

100

If RS=23-2x, ST=9x-5 are the two parts of the whole segment RT and RT=39.

Find RS.

RS=17

200

Segment RT is the whole segment and is equal to 39. 

Segment RS is one part of the whole segment and is equal to 23-2x.

Segment ST is the other part of the whole segment and is equal to 9x-5.

Find what segment RS equals.

17

300

The whole segment is 12x+14.

One part is equal to 6x+1

The other part is equal to 4+x

What does x equal and what is the length of the whole segment?

x=-9/5 

Whole segment= -38/5

400

True or False

When solving for segments, we are supposed to set one part of the segment equal to another part and the whole.

Ex. part=part+whole

False

When solving for segments, it should be 

part+part=whole

500

One part of a whole segment is 3x+9 and another part is 6x-4 and the whole segment equals 22x+12. 

What is the value of x?

x=-7/13

Distance and Midpoint

100

Find the midpoint of segment AB if A(-3,8) and B(-7,-6).

(-5,1)

200

If K is the midpoint of segment JL, JK=8x+11 and KL=14x-1, Find JL.

JL=54

300

Find the distance between the two points. (Round to the nearest hundredth. 

(-1,2) & (4,0)

5.39

400

What did I say was the first thing to do when solving a midpoint or distance problem?

write (x1,y1) and (x2,y2) underneath the points that we are given.

500

Find the coordinates of the midpoint of segment HK if H(-3,8) and K(-7,-6).

(-5,1)

Angle Measures

100

What is a right angle?

a 90 degree angle

200

What is an obtuse angle?

An angle between 90 degrees and 180 degrees

300

What is a straight angle?

a straight line, 180 degrees

400

If ray KM bisects Angle JKL, Angle JKL=92 and MKL is 5x+1. Find the value of x.

x=9

500

Angle Z and Angle W form a linear pair. 

Angle Z=108 Angle W=4x+12

What is the value of x?

x=15

Angles Relationships

100

True or False

Vertical Angles add up to 180 degrees

False

200

What are complementary angles?

Two angles that add up to 90 degrees

300

What are vertical angles?

two angles that are across from each other on intersecting lines. these two angles are congruent

400

Angle A and Angle B are supplementary angles. Angle A=12x+10 Angle B=4+6x. What is the angle measure for Angle B? (Round your final answer to the nearest hundredth. 

59.33 degrees

500

What does the upside-down T stand for?

This tells us that it is perpendicular
