GEOMETRY CA2 REVIEW

Front

What is a translation in geometry?

Back

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

Front

What is the rule for translating a point (x, y) 7 units right and 1 unit down?

Back

The rule is (x, y) → (x + 7, y - 1).

Front

How do you find the slope of a line perpendicular to a given line?

Back

The slope of a line perpendicular to another is the negative reciprocal of the slope of the original line.

Front

What is the slope of the line represented by the equation y = -\frac{1}{5}x + 8?

Back

The slope is -\frac{1}{5}.

Front

If a triangle has a base of 12 cm, what is the triangle inequality theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

What is the definition of a reflection in geometry?

Back

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

Front

What is the formula for the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}.

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.
