Geometry AC Flashcards
Congruent
Identical shapes where they are exactly the same
Perpendicular Bisector
To cut a figure in half and have a a 90 degree angle
Equilateral
Equal side lengths in a figure
Equalangular
Equal angles in a figure
Regular
Equilateral + Equalangular
Line segment
A segment of a line with two endpoints
Radius
A line from the center of a circle to the side of a circle
Diameter
A line that cuts a circle in half
Perpendicular
When a line intersects with another and it forms a 90 degree angle
Inscribe
To form a polygon within a circle
Midpoint
The middle of a line segment/ray/line
Quadrilateral
A polygon with a four sides
Rhombus
A quadrilateral made of two regular triangles
Angle Bisector

Parallel line
A line that doesn’t intersect with another line
Equidistant
Equal distance
Hexagon

A three sided construction
Endpoint
Endpoint on a ray/line segment
Arc
Part of a circle
Polygon
A shape
Angle Bisect/or
To bisect angle
Bisect
To cut in half
Rhombus
Two congruent triangles reflected on top of each other
Right angle
A 90 degree angle
Square/Regular quadrilateral
Two sets of parallel lines & 4 90 degree angle
Circumcenter
A point where 3 perpendicular bisectors meet in a triangle. It is the same distance to each corner of the triangle that the 3 points make
Diagonal
A line at a diagonal
