SY25 Geometry IA2 (Final) Review B

Front

What is the result of translating a point (x, y) vertically by -2 units?

Back

The new coordinates will be (x, y - 2).

Front

What is the formula to calculate the number of ways to award first, second, and third prizes to n different organizations?

Back

The formula is n! / (n - r)!, where r is the number of prizes (3 in this case).

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If m ∠ L = 90° and m ∠ K = 55°, what is the relationship between these angles?

Back

They are complementary angles, as their sum is 145°.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What theorem can be used to prove triangle congruence with two angles and a non-included side?

Back

The AAS (Angle-Angle-Side) theorem can be used.

Front

What does SSA stand for in triangle congruence?

Back

SSA stands for Side-Side-Angle, which does not guarantee triangle congruence.

Front

How do you find the measure of an unknown angle in a triangle?

Back

Subtract the sum of the known angles from 180°.

Front

What is the definition of a translation in geometry?

Back

A translation is a transformation that moves every point of a shape the same distance in a specified direction.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is 90°, and the sum of the other two angles is 90°.
