This transformation slides a figure without changing its size or orientation.
What is a translation?
Two figures with the same shape but different sizes are called these.
What are similar figures?
A polygon with three sides.
What is a triangle?
A solid with two parallel congruent circular bases.
What is a cylinder?
The distance around a circle.
What is circumference?
This transformation flips a figure over a line called the line of reflection.
What is a reflection?
This number tells how much a figure is enlarged or reduced in a dilation.
What is the scale factor?
A quadrilateral with exactly one pair of parallel sides.
What is a trapezoid?
A solid with six congruent square faces.
What is a cube?
A point where two lines intersect.
What is a vertex?
This transformation turns a figure around a fixed point.
What is a rotation?
In similar figures, corresponding angles have this relationship.
What are they congruent?
A quadrilateral with all sides equal and all angles right angles.
What is a square?
A solid with one circular base and a vertex.
What is a cone?
The longest side of a right triangle.
What is the hypotenuse?
This transformation changes the size of a figure but keeps its shape the same.
What is a dilation?
In similar figures, corresponding side lengths have this relationship.
What are they proportional?
A polygon with eight sides.
What is an octagon?
This solid has triangular faces that meet at a single vertex.
What is a pyramid?
A line that touches a circle at exactly one point.
What is a tangent?
A transformation that preserves distance, angle measure, and size is called this.
What is a rigid motion (or isometry)?
This theorem states that a line parallel to one side of a triangle divides the other two sides proportionally.
What is the Triangle Proportionality Theorem?
The sum of the interior angles of a triangle
What is 180 degrees?
A rectangular prism has this many faces.
What is six?
The sum of the interior angles of any polygon can be found using this expression.
What is (n−2)×180?
