Angles
An angle that is less 90 degrees
Acute
Pairs of angles on one side of a transversal, inside the two lines it intersects.
Consecutive interior angles
All sides of a triangle are equal
Equilateral
How many degrees are in a quadrilateral
360
A flip over the x axis is an example of a
Reflection
Two angles that add to 180 degrees
Supplementary Angles
A pair of angles located between two lines (the interior) and on opposite sides (alternate) of a transversal line that intersects them
Alternate interior angles
Acute
How many degrees inside an octagon?
1080
A turn around the origin is an example or a
Rotation
Angles that are side by side
Adjacent
A pair of angles on the outer side of two lines intersected by a transversal, positioned on opposite sides of that transversal
Alternate exterior angles
One angle of the triangle is larger than 90 degrees
Obtuse
How many degrees inside a 13-gon
1980
A slide across the coordinate plane is an example of a
Translation
Two angles that are across from each other and congruent
Vertical Angles
Pairs of angles in the same relative position (matching corners) at each intersection where a straight line (transversal) crosses two other lines
Corresponding angles
Two sides of a triangle are equal in measure
Isosceles
How many degrees inside a decagon
1440
When rotating a figure, which way does the figure rotate
Counterclockwise
Two angles that add to 90 degrees
Complementary Angles
The line that intersects the parallel lines is called a
Transversal
No sides of a triangle are equal in length
Scalene
Square QRST is congruent to Square ABCD
Angle R is congruent to which Angle?
