Plane Geometry

Front

What is a point in geometry?

Back

An exact location in space with no length or width.

Front

What is a line in geometry?

Back

A straight path that extends infinitely in both directions with no endpoints.

Front

What is a line segment?

Back

A part of a line that has two endpoints.

Front

What is a ray in geometry?

Back

A part of a line that has one endpoint and extends infinitely in one direction.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through the points (3, 7) and (7, 2)?

Back

Front

What is the measure of angle 4 if angle 1 = 27°?

Back

Angle 4 = 27°.

Front

What is a transformation in geometry?

Back

A change in the position, size, or shape of a figure.

Front

What are the three main types of transformations?

Back

Translation, Rotation, Reflection.

Front

What is a reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.
