Flashcardziz: Mid-term Review Part 2

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

If DF = 5x + 1, how do you find XF?

Back

To find XF, you need to solve for x using the properties of the parallelogram and then substitute x back into the equation.

Front

What is the value of a if the options are 113, 150, 210, 330 and the answer is 150?

Back

The value of a is 150.

Front

If FN = 29, how do you find the value of r?

Back

You need to use the relationship between FN and r, which may involve solving an equation.

Front

What theorem states that ∠ 1 ≅ ∠ 8 when line p intersects lines a and b, with a parallel to b?

Back

The theorem is the Alternate Exterior Angles Theorem.

Front

What is the slope of a line perpendicular to y = -3x + 2?

Back

The slope of a line perpendicular to y = -3x + 2 is the negative reciprocal of -3, which is 1/3.

Front

How do you write the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope.

Front

What is the Alternate Interior Angles Theorem?

Back

The Alternate Interior Angles Theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles is equal.

Front

What is the Corresponding Angles Postulate?

Back

The Corresponding Angles Postulate states that if two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

How do you determine if two lines are parallel?

Back

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