Basics of Geometry

Part of a line. Has two endpoints and includes all of the points in between.

• Point

• Angle

• Line

• Line Segment

Name 4 collinear points

• HMNO

• IKNO

• MJOL

• HNKI

What is this Symbol called?

• Congruent

• Equal

• Parallel Lines

• Angle

Given that C is between A and B, which Segment Addition statement is correct?

• AC + AB = CB

• AC + CB = AB

• AB + BC = AC

• CA + CB = CA

Tell whether the angles are complementary or supplementary. Then find the value of x.

• Complementary; x=25

• Complementary; x=5

• Supplementary; x=25

• Supplementary; x=5

1. Find X

• 28

• 5

• 55

• 40

Supplementary Angles...

• add up to 90 degrees

• add up to 180 degrees

• are equal to each other, share a common vertex, and sides are opposite rays

• are next to each other and share a common vertex & ray

Vertical Angles...

• add up to 90 degrees

• add up to 180 degrees

• are equal to each other, share a common vertex, and sides are opposite rays

• are next to each other and share a common vertex & ray

• (3,7)

• (9,11)

• (5,2)

• (7,3)

What is the circumference?

• 48

• 96
