Geometry Semester 1 Review

Front

What are parallel lines?

Back

Lines that never intersect and are always the same distance apart.

Front

What is the scale factor in dilation?

Back

The ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

What does it mean if the scale factor (k) is between 0 and 1?

Back

The image is a reduction of the original figure.

Front

What is the hypotenuse in a right triangle?

Back

The longest side of a right triangle, opposite the right angle.

Front

What is the Transitive Property of Equality (POE)?

Back

If a = b and b = c, then a = c.

Front

What is the Linear Pair Postulate?

Back

If two angles form a linear pair, they are supplementary (add up to 180 degrees).

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always congruent.

Front

What is the Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

What is the Alternate Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

How many angles are needed to show congruency using Transitive POE?

Back

Three angles.
