Geometry Final Exam REVIEW

Front

What is the rule for reflection across the line x = 3?

Back

To reflect a point across the line x = 3, subtract the x-coordinate of the point from 6 and keep the y-coordinate the same.

Front

What is the equation to solve for x in tan(46) = 17/x?

Back

x = 17/tan(46).

Front

How do you find the missing angle in a triangle if two angles are known?

Back

Use the fact that the sum of angles in a triangle is 180 degrees. Subtract the sum of the known angles from 180.

Front

How is Quadrilateral EFGH translated to E'F'G'H'?

Back

The translation is 6 units down and 3 units left.

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 formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What is the area formula for a triangle?

Back

Area = 1/2 * base * height.

Front

What is the difference between a reflection and a translation in geometry?

Back

A reflection flips a shape over a line, while a translation slides a shape to a new position without changing its orientation.

Front

What is the definition of a quadrilateral?

Back

A quadrilateral is a polygon with four sides and four angles.
