Point
A point is a location without shape of size. It has no dimensions.
The silver button represents a “point”
T
Line
A line has length and points and it has no width or thickness.
The edge of the iPhone represents a “line”
A
B
Line Segment A line segment is a straight line
which links two points without extending beyond them.
The edge of the phone represents a “line segment”. The line starts at point C and ends at point D without extending.
C
D
Ray A ray is a line with a start point but
no end point.
∞
The phone cord represents a “ray” because it is its start point and it extends infinitely. E
F
Opposite Rays Opposite rays must be collinear.
The bottom represents “opposite rays” because G is between H and I, then GH and GI.
G IH
Parallel Lines Parallel lines are two lines on a
plane that never meet and its always the same distance apart.
The parallel lines is represented by the left and right sides of the phone, J and K.
J K
Perpendicular Lines Perpendicular lines is lines meet or
crosses at right angles. (90˚)
This represents Perpendicular lines because the lines L and M meet.
L
M
Acute Angle A acute angle is an angle whose
measure is less than 90˚.
The gap between the two phones represents an acute angle because the measure is less than 90˚.
N P
O
Obtuse Angle A obtuse angle is an angle whose
measure is between 90˚ and 180˚.
This represents an “obtuse angle” because the measure of angle QRS is between 90˚ and 180˚.
Q
R
S
Right Angle A right angle is an angle whose
measure is exactly 90˚.
This phone represents a right angle because the measure of the corner is exactly 90˚
T

Vertical Angles A vertical angle is a pair angles
whose sides form opposite rays.
≅
This represents “vertical angles” because the sides form opposite rays.
12
Adjacent Angles A adjacent angle is a pair of angles
with a shared vertex and a common side but do not have overlapping interiors.
This represents an “adjacent angle” because it has a pair of angles , 3 and 4, and a common side.

Intersecting Lines Intersecting lines is the point
where two lines meet or cross.
This represents “intersecting lines” because lines A and B intersected and point W is where the two lines crossed.
A
B
W
Intersecting Planes Intersecting planes is two planes
that meet in a single line.
This represents “intersecting planes” because planes C and D meet in line XY
C
DX
Y
Supplementary Angles A supplementary angle is a pair of
angles whose sum is 180˚.
This represents a “supplementary angle” because angle 5 and 6 has a sum of 180˚.
56
Complementary Angles A complementary angle is a pair of
angles whose sum is 90˚.
This represents a “complementary angle” because angles 7 and 8 have a sum of 90˚.
