WAM “Writing About
Math”What is the difference between similar and
congruent? Illustrate and explain.

Transformation:
• The mapping, or movement, of all the points of a figure in a plane according to a common operation.

Translation:
• A transformation that "slides" each point of a figure the same distance in the same direction.

Angle of Rotation:
• The amount of rotation about a fixed point.

Congruent Figures:
• Figures that have the same size and shape.
![Page 7: WAM Writing About Math](https://reader035.fdocuments.net/reader035/viewer/2022062908/5a4d1b957f8b9ab0599c360c/html5/thumbnails/7.jpg)
Dilation:
• Transformation that changes the size of a figure, but not the shape.

Reflection:
• A transformation that "flips" a figure over a line of reflection.

Reflection Line:
• A line that is the perpendicular bisector of the segment with endpoints at a pre-image point and the image of that point after a reflection.

Rotation:
• A transformation that turns a figure about a fixed point through a given angle and a given direction.

Similar Figures:
• Figures that have the same shape but not necessarily the same size.

Scale Factor:
• The ratio of any two corresponding lengths of the sides of two similar figures.

Homework
• Students will translate the following figure A (4, 3), B (6, 7), & C (8, 3).
• ( X-3) & (y-5)

Same-Side Interior Angles: • Pairs of angles formed when a third line (a
transversal) crosses two other lines. • These angles are on the same side of the
transversal and are between the other two lines.
• When the two other lines are parallel, same-side interior angles are supplementary.
![Page 15: WAM Writing About Math](https://reader035.fdocuments.net/reader035/viewer/2022062908/5a4d1b957f8b9ab0599c360c/html5/thumbnails/15.jpg)
Same-Side Exterior Angles: • Pairs of angles formed when a third line (a
transversal) crosses two other lines. • These angles are on the same side of the
transversal and are outside the other two lines.
• When the two other lines are parallel, same-side exterior angles are supplementary.

Alternate Exterior Angles: • Alternate exterior angles are pairs of angles
formed when a third line (a transversal) crosses two other lines.
• These angles are on opposite sides of the transversal and are outside the other two lines.
• When the two other lines are parallel, the alternate exterior angles are equal.

Alternate Interior Angles: • Alternate interior angles are pairs of angles
formed when a third line (a transversal) crosses two other lines.
• These angles are on opposite sides of the transversal and are in between the other two lines.
• When the two other lines are parallel, the alternate interior angles are equal

Transversal:
• A line that crosses two or more lines.

Linear Pair:
• Adjacent, supplementary angles. Excluding their common side, a linear pair forms a straight line.

Corresponding Sides:
• Sides that have the same relative positions in geometric figures.

Corresponding Angles:
• Angles that have the same relative positions in geometric figures.
