Front

What is the distance formula in geometry?

Back

The distance formula is given by: d = √((x2 - x1)² + (y2 - y1)²), which calculates the distance between two points (x1, y1) and (x2, y2) in a coordinate plane.

Front

Define corresponding angles in geometry.

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What is the definition of a triangle's rotation?

Back

A triangle's rotation is a transformation that turns the triangle around a fixed point (the center of rotation) by a certain angle in a specific direction.

Front

How do you find the length of a segment in geometry?

Back

To find the length of a segment, use the distance formula or measure it directly if it is drawn on a graph.

Front

What is the significance of alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal, which is a key concept in proving lines are parallel.

Front

What does it mean for angles to be supplementary?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

Explain the concept of a transformation in geometry.

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

Define the term 'transversal' in geometry.

Back

A transversal is a line that intersects two or more lines at different points, creating various angle relationships.
