Means: same size, same shape
Equal
Congruent
An angle that measures 90o
Acute angle
Obtuse angle

Right Angle
Match the vocabulary word with its definition:
Congruent angles
two angles whose measures have a sum of 90 degrees
a pair of adjacent angles whose noncommon sides are opposite rays
two angles whose measures have a sum of 360 degrees
angles that have the same measure
Solve for x
x = 56°
x = 66°
x = 156°
x = 166°
An angle with a measurement greater than 90o but less than 180o
Right Angle
Obtuse Angle
Acute Angle
Angle

Define reflection symmetry.
one half of the shape is a reflection of the other half
the shape still looks the same after being rotated less than 360 degrees
a polygon with four sides
What is rotational symmetry?
the shape still looks the same after being rotated less than 360 degrees
