Angles Project
pd.5
By:Chrishard,Odrae,Justin
Definitions
Right Angle-exactly 90 degrees.
Example:
X+62=90
-62 -62
X=28
Definitions
Acute Angle-less than 90 degrees
Definitions
Obtuse-greater than 90 degrees and less
than 180 degrees.
Definitions
Straight-exactly 180 degrees.
Example:
Y+77=180
-77 -77
Y=
Definitions
Complementary-the sum of the measures of two
angles is 90 degrees.
Example:
X + 50=90
-50 -50
X = 40
Definitions
Supplementary Angle-the sum of the
measures of two angles is 180 degrees.
Example:
X + 75 = 180
- 75 - 75
x = 105
Definitions
Vertical Angles- when two lines intersect and
form two pairs of opposite angles that are
congruent.
Example:
If “D” equals 20 then
“B” equals 20.
If “A’’ equals 60 then
“C” equals 60.
Definitions
Adjacent Angles-two angles that share a
vertex and a common side do not over-lap.
Example:
The arrow is pointing at
the vertex.
And this arrow is
pointing at 2 square which mean they are
both 90 degrees.
