Which angles are interior angles?
3, 4, 5, 6
this is a line that intersects two or more lines
Transversal
this is the sum of the interior angles of a triangle
180 degrees
This is the formula that is used to find the sum of the interior angles of polygons
180 (n-2)
This is how to tell if two triangles are similar
all of the angles will be congruent
Angle 7 measures 67 degrees, then angle 5 measures this...
113 degrees
These are the angles inside of a polygon
Interior Angles
this is the value of x
65 degrees
This is the value of x
163
True of false, these triangles are similar
true
Angle 7 measures 67 degrees, so angle 1 measures this..
113 degrees
Convex
This is the value of x
71 degrees
This is the value of x
120
True or false, these triangles are similar
true
These angles all have the same measurement as angle 1...
4, 5, 8
This type of polygon has all sides that are congruent and all interior angles are congruent.
Regular polygon
This is the value of x
109 degrees
this is the measure of one angle inside of a regular octogon
135 degrees
True or false, these triangles are similar
true
This is the value of x...
