Test 1(Euclidean Geometry) Flashcards
Acute
An angle with a measure less than 90 degrees
Supplementary
2 angles whose sum is 180 degrees
Vertical Angles
2 nonadjacent angles formed by 2 intersection sides; vertical angles are congruent
Complementary
2 angles whose sum is 90 degrees
Intersection
Where two figures cross
-2 lines intersect at a point
-A line and a plane intersect at a point
-2 planes intersect at a line
Straight
An angle with a measure of 180 degrees
Linear Pair
A pair of adjacent angles that form a line
Point
A location without shape or size
Bisect
To cut into 2 congruent parts
Angle
Two non-collinear rays with a common vertex
Line segment
Part of a line bounded by two endpoints
Adjacent angles
2 angles with a common vertex and side but not common interior points
Right
An angle with a measure of 90 degrees
Protractor
Tool used to measure angles (unit=degrees)
Space
The set of all points
Ray
A part of a line with one endpoint
Betweenness of Points
When one point is between 2 endpoints
Coplanar
Points or lines all in the same place
Congruent
the same size and shape; equal
Collinear Points
Points all on the same line; in the same line
Obtuse
An angle with a measure greater than 90 degrees
Congruent Segments
Segments with the same measure
Plane
A flat surface that extends forever in both directions
Perpendicular lines
2 lines that intersect to form right angles
Line
A set of points that extend forever in both directions
Opposite Rays
2 rays going in opposite directions that share a common endpoint
