Transformations
This transformation slides a figure to a new position.
What is translation?
When two figures have the same shape but are different sizes.
What are similar figures?
This pair of angles, found inside the parallel lines on opposite sides of the transversal, is congruent.
What are alternate interior angles?
These adjacent angles sharing a common side add up to 180 degrees.
What are linear pairs?
The measure of corresponding angles in similar triangles.
What are congruent angles?
This transformation turns a figure around a fixed point.
What is a rotation?
Two figures that have the same size and shape.
What are congruent figures?
This pair of angles, found in the same relative position when a transversal cuts parallel lines, is congruent.
What are corresponding angles?
This missing angle, forming a linear pair with a 130-degree angle, measures:
What is 50 degrees?
If two triangles are similar, if one triangle has an angle of 32 degrees, the corresponding angle in the other triangle is:
What is 32 degrees?
This transformation flips a figure over a line.
What is a reflection?
Two figures that have congruent corresponding angle measures and proportional corresponding sides.
What are similar figures?
The sum of any two interior angles on the same side of the transversal in parallel lines.
What is 180 degrees?
The angle measure of an angle vertical to an 82-degree angle.
What is 82 degrees?
When triangles are similar, the ratio of their corresponding sides is:
What is proportional?
This transformation can change the size of a figure while keeping its shape.
What is a dilation?
This changes the size of a figure, therefore creating a similar figure.
What is a scale factor?
Lines that never meet and are always the same distance apart.
What are parallel lines?
This angle forms a supplementary pair with a 110-degree angle.
What is a 70-degree angle?
When two pairs of corresponding angles are congruent, the triangles are proven to be similar by:
What is angle-angle similarity?
This type of transformation preserves angle measurements and side lengths.
What are rigid transformations?
One or more transformations performed in a certain order, creating similar figures.
What is a sequence of transformations.
If alternate exterior angles are congruent, the lines are confirmed to be this.
What are parallel lines?
In a triangle with angles of 90 degrees and 40 degrees, the missing angle measures:
What is 50 degrees?
When two triangles are similar, the ratios of these are equal.
What are the corresponding sides?
