Basic Geometry Angles

Define complementary angles.

• Two angles that are adjacent to each other

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees

• Two angles that are equal in measure

Explain what a straight angle is.

• A straight angle measures 45 degrees.

• A straight angle measures 360 degrees.

• A straight angle measures 180 degrees.

• A straight angle measures 90 degrees.

Define vertical angles.

• A pair of adjacent angles formed by two intersecting lines that are congruent.

• A pair of opposite angles formed by two parallel lines that are congruent.

• A pair of angles formed by two intersecting lines that are supplementary.

• A pair of non-adjacent angles formed by two intersecting lines that are congruent.

What is the measure of a reflex angle?

• Exactly 180 degrees

• Between 0 and 90 degrees

• Less than 90 degrees

• Between 180 and 360 degrees

Explain what a supplementary angle is.

• A supplementary angle is formed when two angles add up to 90 degrees.

• A supplementary angle is formed when two angles add up to 180 degrees.

• A supplementary angle is formed when two angles add up to 360 degrees.

• A supplementary angle is formed when two angles add up to 270 degrees.

• Alternate Interior Angles
