Geometry Flashcards
Who is the “Father of Geometry?”
Euclid of Alexandria
What kind of Mathematician was the “Father of Geometry?”
Greek
Two different rays that have the same initial point.
Angles
Two angles with common vertex and share a common side.
Adjacent angles
If two angles are adjacent and their non-common side forms a straight angle.
Linear Pair
Has a common vertex but not adjacent, always congruent.
Vertical Angle
The sum of the measurement of angles in 90 degrees.
Complimentary
The sum of the measurement of angles in 180 degrees.
Suplimentary
How many degrees does the angles of linear angles add up to?
180 degrees
Lines that stay the same distance apart and never cross.
Parallel lines
Lines that are on different planes and do not intersect.
Skew lines
Lines that intersect and form right angles.
Perpendicular lines
The intersecting line that cuts the parallel lines is called:
Transversal
The line that intersects two coplanar lines at two distinct points:
Transversal
The angles that are formed by transversal that lie on the outer side of the parallel lines but on the opposite sides of the transversal
Alternate Exterior Angles
