Point

• A point is a dot on a plane or a endpoint for a line segment or a ray

Like earth is a point in space

Line

• A line is never ending• https://www.travelblog.org/Photos/511493

•

• This train track may look like it goes on forever but it don’t

Plane

• A plane is space that points and line segments can be on• http://serendip.brynmawr.edu/exchange/silent-space

• Space is a never ending plane with the planets as the points

Segment

• A segment is like a line but is not ever going• http://www.vt.edu/spotlight/innovation/2012-04-09-pythons/willson.html

• This snake is not going on forever it is just here to there

Ray

• A ray is only going on forever http://wattsupwiththat.com/2012/07/17/hansens-death-trains-now-with-extra-scary-coal-fallout/

• This Union Pacific coal train looks like it goes on forever but since the locomotives are visible it looks like a ray

Collinear Points

• 2 or more points on the same line• http://skyscraper.org/EXHIBITIONS/WALL_STREET/east_end_2.php

• The interceptions in the circle can be collinear points because the interceptions are on the same road

Acute angles

• Angles that are less then 90 degrees• http://commons.wikimedia.org/wiki/File:Railroad_switch_labelled.png

• This railroad switch is a acute angle because it is not a 90 degree angle

Obtuse angles

• Angles that is greater than 90 degrees• http://pitchingtips.org/category/1/page/424/

• This curve is wide and wide than a 90 degree angle so it is a obtuse

Right angles

• A angle that is 90 degrees• http://ops.fhwa.dot.gov/aboutus/one_pagers/arterial_mgmt.htm

• The part of the intersection that the arrow is pointing at is the part that is 90 degree

Perpendicular Lines

• Two lines that intercept and form all right angles• Two lines that intercept to form all right angles

Complementary Angles

• Two angles that are a adjacent and form a 90 degree angle• http://emiliefrazier.blogspot.com/2011/10/complimentary-angles.html

• When the clock says 3 o’clock and if the second hand is in-between the two arms it will make a complementary angle

Supplementary Angles

• Two adjacent angles that form a 180 degree angle• http://christiedaugherty151.wix.com/geometry#!chapter-2

• If you look at the body of the airplane and the wing it will look like a supplementary angle

Vertical Angles

• Vertical angles share a point but not a side

Acute Triangle

• A acute Triangle is a triangle that has only acute angles

Obtuse Triangle

• A obtuse triangle has only one obtuse angle

Equilateral Triangles

• A equilateral triangle have equal sides

Isosceles Triangles

• Triangles with only two equal sides

Scalene Triangle

• Triangles with no equal sides

Right Triangle

• A triangle with one right angle

Circle

• Diameter-a line going from one side of the circle to the other side going through the middle of the circle• Radius-half of the diameter• Cord-a line going from one side of the circle but not going through the

center of the circle• Secant-a line that touches in two points but keeps going• Tangent-a line that only touches the circle at one point and keeps

going
