Midterm Review Geometry

Front

What is a reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What is the rule for translating a point (x,y) 4 units to the right and 5 units up?

Back

(x+4, y+5)

Front

What is the definition of translation in geometry?

Back

A transformation that moves every point of a figure the same distance in a specified direction.

Front

What are supplementary angles?

Back

Angles that add up to 180°.

Front

What is the image of the point Z(4, -2) after a 180-degree rotation about the origin?

Back

Z'(-4, 2)

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point.

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a figure over a line, while a rotation turns it around a point.

Front

What is the definition of a transformation in geometry?

Back

An operation that moves or changes a shape in some way.

Front

What is the image of the point (3, 5) after a translation of 4 units right and 5 units up?

Back

Front

What is the definition of a line of symmetry?

Back

A line that divides a figure into two mirror-image halves.
