Front

What is the rule for a reflection over the x-axis?

Back

The rule for a reflection over the x-axis is given by the transformation: f(x, y) = (x, -y).

Front

What is a median in a triangle?

Back

A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which can be determined using criteria such as SSS, SAS, ASA, AAS, or HL.

Front

What is an altitude in a triangle?

Back

An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is the rule for rotating a point 270 degrees counter-clockwise about the origin?

Back

The rule for rotating a point (x, y) 270 degrees counter-clockwise about the origin is: (x, y) → (y, -x).

Front

What is the definition of a triangle?

Back

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

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

What is the difference between a median and an altitude in a triangle?

Back

A median connects a vertex to the midpoint of the opposite side, while an altitude connects a vertex to the opposite side at a right angle.

Front

What is the formula for the area of a triangle?

Back

The area (A) of a triangle can be calculated using the formula: A = 1/2 * base * height.

Front

What is the definition of congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size, allowing for rotation, reflection, or translation.
