Basics of Geometrical Reasoning

Vertically opposite angles ................................

• add up to 180

• are complementary angles

• are congruent

• are co - interior angles

What type of angles are h and g?

• co interior angles

• exterior angles

• alternate angles

• angles on a straight line

What is the angle sum of a quadrilateral?

• 180

• 540

• 620

• 360

Why are the angles congruent?

• They are complementary angles

• They are corresponding angles

• They are alternate angles

• They are opposite angles

What type of angles are these? There are two answers.

• angles on a straight line

• adjacent supplementary angles

• non adjacent supplementary angles

• co interior angles

What type of angles are these?

• alternate angles

• corresponding angles

• interior angles

• exterior and interior angle

Select a property that is true for any triangle.

• transversal

• parallel

• intersection

What is meant by perpendicular?

• Two lines meeting at 90 degrees.

• A complete turn

• A pair of lines apart from each other.

• straight
