geometric constructions Flashcards
1
Q
- Has no beginning or
end. - Continues indefinitely
in both directions. - Can be illustrated by
drawing arrows at
each end.
A
Line
2
Q
- Has a beginning point
and an end point. - Line segments on a
shape are called sides. - Can be found in many
shapes.
A
Line segment
3
Q
Lines in the same
plane that do not
intersect or cross
each other.
A
Parallel
4
Q
- Has a beginning point
but no end point.
A
Ray
5
Q
Two or more lines that
meet at a point.
A
Intersecting
6
Q
Perpendicular lines
form a right or 90
degree angle.
A
Perpendicular
7
Q
- Made up of two rays
with the same start
point. - The start point is
called the vertex. - The two rays are
called the sides of the
angle.
A
Angles
8
Q
Are Parallel and equal
180 degrees.
A
Zero angles
9
Q
Two rays that create a
90 degree angle.
A
right angle
10
Q
Two rays that have a
smaller angle than a
right angle.
A
Acute angle
11
Q
- Angles larger than a
right angle and
smaller than two right
angles.
A
Obtuse angle
12
Q
Angles equal to two
right angles.
A
Straight angle
13
Q
- Two angles that sum
to a straight angle
A
Supplementary angles
14
Q
- Two angles that sum
to one right angle
A
Complementary angles
