Geometry: Semester 1 Final Review

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the types of transformations?

Back

The main types of transformations are translation, rotation, reflection, and dilation.

Front

What is the rule for translating a shape 3 units right and 2 units up?

Back

The rule is (x, y) -> (x + 3, y + 2).

Front

What is the rule for reflecting a shape over the x-axis?

Back

The rule is (x, y) -> (x, -y).

Front

What is the rule for rotating a shape 90 degrees clockwise around the origin?

Back

The rule is (x, y) -> (y, -x).
