Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are linear pairs of angles?

Back

Linear pairs are two adjacent angles that form a straight line, meaning their measures add up to 180 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What does it mean to reflect over the x-axis?

Back

Reflecting over the x-axis means flipping a figure over the x-axis, changing the sign of the y-coordinates of the points.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

How do you find the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. You can find an unknown angle by subtracting the sum of the known angles from 180.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects. They are equal when the lines are parallel.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal when the lines are parallel.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that are on the same side of the transversal and inside the two lines it intersects. They are supplementary when the lines are parallel.
