What is the key characteristic of similar triangles?

• They have different angles.

• They are always congruent.

• They have the same angles.

• They have the same side lengths.

Why is it helpful to draw separate diagrams when solving geometry problems?

• To make the problem more complex.

• To avoid using mathematical reasoning.

• To increase the number of diagrams.

• To visualize the problem more clearly.

What is a cyclic quadrilateral?

• A quadrilateral with all angles equal.

• A quadrilateral with no right angles.

• A quadrilateral with opposite angles adding up to 180 degrees.

• A quadrilateral with all sides equal.

How do opposite angles in a cyclic quadrilateral relate to each other?

• They add up to 180 degrees.

• They are equal.

• They are complementary.

• They add up to 90 degrees.

What is the significance of proving two angles equal in two triangles?

• It proves the triangles are congruent.

• It proves the triangles are similar.

• It proves the triangles are identical.

• It proves the triangles are different.

Why is it important to provide mathematical reasons in your solutions?

• To confuse the examiner.

• To make the solution longer.

• To ensure clarity and correctness.

• To avoid using diagrams.

What is a recommended strategy for improving your exam performance?
