100
This is the name for the figure created after a transformation takes place.
What is an image?
100
This is what two angles are called when their angle measures add up to 90 degrees.
What are complementary angles?
100
This is the term for a quadrilateral with opposite sides that are parallel and equal in length.
What is a parallelogram?
100
This is the type of symmetry a figure has if it can be folded along a line and the two halves match.
What is reflection symmetry?
100
This is a statement that can be proven based on postulates, definitions, and previously proven ideas.
What is a theorem?
200
This is the type of transformation that flips a figure over a line.
What is a reflection?
200
This is a line that cuts an angle into two equal parts.
What is an angle bisector?
200
This is a four-sided figure with four right angles whose sides might or might not be all equal.
What is a rectangle?
200
This is the name of the line that divides a figure into two mirror-image halves.
What is the line of symmetry?
200
This is the term for a straight path that has no thickness and extends in both directions forever.
What is a line?
300
This is a transformation where a figure is turned around a fixed point.
What is a rotation?
300
This is the term used for two lines that never intersect and are always equidistant.
What are parallel lines?
300
This is the term for a polygon that is both equilateral and equiangular. (hint: term for all types of shapes that fit this description)
What is a regular polygon?
300
This type of symmetry involves turning a figure around a central point and having it look the same.
What is rotational symmetry?
300
This is the term for a part of a line bounded by two endpoints.
What is a line segment?
400
This is what it's called when a transformation that maintains the size and shape of a figure.
What is a rigid transformation?
400
This is what you call a line that goes through the midpoint of a segment and creates a 90 degree angle.
What is a perpendicular bisector?
400
This is a the term used to find any point on the outside of a circle to its midpoint.
What is the radius?
400
This is how many lines of symmetry a rectangle has.
What is 2?
400
This is a rigid transformation that takes all lines and points a certain direction and distance.
What is a translation?
500
This is the scale factor for these triangles from triangle 1 to triangle 2.
What is 3/2 or 1.5?
500
This is the name of a line that is drawn through a shape to create two other shapes to help solve a geometric problem.
What is an auxiliary line?
500
This is the term given to two figures that have the same shape but their sizes are proportional.
What are similar figures?
500
This is the rotational symmetry degree that an equilateral triangle has.
What is 120 degrees?
500
This is the term that describes the length and direction of a translation.
