What is a line of reflection in geometry?

Back

A line of reflection is a line across which a figure is reflected to create a mirror image. Points on one side of the line are equidistant from the line as their corresponding points on the other side.

What does the symbol '→' represent in logic?

Back

In logic, the symbol '→' represents implication. It indicates that if the first statement (antecedent) is true, then the second statement (consequent) must also be true.

What is the relationship between the sides of a right triangle?

Back

In a right triangle, the lengths of the sides are related by the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end. The segments are called sides, and the points where they meet are called vertices.

What does 'reflection across the x-axis' mean?

Back

Reflection across the x-axis means that for every point (x, y) in the plane, the reflected point will be (x, -y). This creates a mirror image of the figure over the x-axis.
