Proofs
<1+<2=90
What is Addition
Need to know the center of rotation (usually a point), The direction (CW or CCW), And the Number if degrees rotated.
What is Rotation
/
What is Diagonal Symmetry
coplaner lines that never intersect
What is a Parallel Line
An Angle that measures exactly 90°
What is a Right Angle
<2=90-<1
What is Subtraction
Need to know the line of the reflection (⊥ Bisector)
What is Reflection
__
What is Horizontal Symmetry
A line that intersects parallel lines at diffrent points
What is a Transversal Line
When two line or two segmants intersect at one point to form a 90° angle
What is Perpendicular
AB+BC=AC
What is Segmant Addition
Need to know the points to be translated and the translation vector.
What is Translation
Occurs when a figure can be rotated about a point onto itself through a rotation of 0° to 360°.
What is Rotational Symmetry
Angles found inside the parallel lines
What is an Interior Angle
Parts that are equal distance from eachother
What is Equidistant
<1≅<1
What is Reflexive Property
The angle formed by connecting corresponding vertices to the center of rotation.
What is Angle of Rotation
A shape that has a rotational symmetry of 180°
What is Point Symmetry
Angles found outside the parallel line
What is a Exterior Angle
The middle point in a line segment that is equal distance from the end points
What is the Midpoint
if <1=<2, <2=<3, and <1=<3
What is Transitive Property
The insersection between two ⊥ bisectors from the pre-image to its image point
What is the Center of Rotation
The symmetry of a figure that maps onto itself with a degree of 360°
What is Idenity Symmetry
Angles on the oppisote sides of the transversal line
What is a Allernate Interior Angle
A segmant that intersects the midpoint of a line segment and forms a right angle
What is a Perpendicular Bisector
