Geometry QA#2 Review

Front

What is the translation of triangle ABC to triangle A'B'C'?

Back

The translation is given by the transformation (x - 2, y + 9).

Front

What is a counterexample to the statement: Any number divisible by 2 is divisible by 4?

Back

A counterexample is 10 ÷ 2, which equals 5, not divisible by 4.

Front

What additional information is needed to prove \(\Delta ADE \cong \Delta CBE\) by ASA?

Back

You need \(\angle B \cong \angle D\).

Front

What do the slopes of the lines y = -2/3x + 2 and y = 3/2x + 9 indicate about their relationship?

Back

The lines are perpendicular.

Front

What is a counterexample to the statement: If it is a fraction, then it is a number between zero and one?

Back

A counterexample is 3/2, which is greater than 1.

Front

Define translation in geometry.

Back

Translation is a geometric transformation that moves every point of a shape a constant distance in a specified direction.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence.

Front

What is the definition of a counterexample?

Back

A counterexample is an example that disproves a statement or proposition.

Front

What is the relationship between parallel lines?

Back

Parallel lines have the same slope and never intersect.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines intersect at a right angle (90 degrees).
