Basic Geometric Figures
Represents one single position in space and looks like a dot
Point
Two lines that never intersect are called
Parallel Lines
AB + BC = AC
Segment Addition Postulate
Moving figures across the coordinate plane or "sliding" is what kind of transformation
Translation
Supplementary angles add to
180 degrees
A straight path through two points and extends infinitely in both directions
Line
A line that intersects two or more lines are called
Transversal Lines
<BAC + <CAD = <BAD
Angle Addition Postulate
A figure revolving around a fix point either clockwise or counterclockwise is what kind of transformation
Rotation
Complementary Angles Add to
90 degrees
Straight Path that has two end points
Line Segment
What angle relationship is <1 and <6.
Vertical angles
If points A, B, and C all fall on the same line, but point B is directly in the middle what is Point B called
Figures are transformed using a mirror like strategy, what am I called?
Reflection
Vertical angles are __________ to each other
Equal, congruent
Continues infinitely in one direction and has an endpoint.
Ray
<4 is Alternate Exterior to what angle?
<5
This can be a ray, line, or segment that divides the angle into two equal parts
Angle Bisector
Point A(2, 4) is translated 4 units up and 9 units down. what is the coordinates fr the image A'
A'(6,-5)
<A and <B are supplementary angles. <A = 15x +5, <B = 5x +15. What is the value of x?
x = 8
Flat surface, no thickness, and continues infinitely in both directions
Plane
<6 corresponds to what angle?
<8
If Point A,B, and C fall on the same line, and point B is the midpoint with AB= 12. What is the measurement of BC?
BC =12
If A(-2,10) -> A'(0,21) how many units dis this figure translate along with direction.
2 units up and 11 units right
<T and <J and Complementary Angles. if <T = 4x +7, and <J = 7x -5. What is the value of <J.
<J = 51
