Transformations & Triangle Congruence Review

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the rule for translating a point (x, y) to the right by 2 units and down by 1 unit?

Back

The rule is (x + 2, y - 1).

Front

How do you reflect a point (x, y) over the x-axis?

Back

To reflect a point (x, y) over the x-axis, the new coordinates will be (x, -y).

Front

What is the transformation rule for (x, y) to (x - 1, y + 1)?

Back

This transformation represents a translation 1 unit to the left and 1 unit up.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem stating that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the rule for translating triangle ABC to triangle A'B'C' if A(1, 2) translates to A'(3, 1)?

Back

The translation rule is (x + 2, y - 1).

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem used to prove the congruence of right triangles by showing that the hypotenuse and one leg are equal.

Front

How do you reflect a point (6, -3) over the x-axis?

Back

The reflection of (6, -3) over the x-axis is (6, 3).

Front

What is the rule for translating a point (x, y) to the left by 2 units and up by 5 units?

Back

The rule is (x - 2, y + 5).

Front

What does the term 'translation' mean in geometry?

Back

Translation refers to moving a shape or point a certain distance in a specified direction without changing its orientation.
