1.1-1.3 Geometry Review

Front

What are coplanar points?

Back

Coplanar points are points that lie on the same plane.

Front

Provide an example of coplanar points.

Back

A, F, E are coplanar points.

Front

What are non-collinear points?

Back

Non-collinear points are points that do not all lie on the same straight line.

Front

Provide an example of 2 non-collinear points.

Back

F and B are non-collinear points.

Front

What is a ray in geometry?

Back

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

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is an angle in geometry?

Back

An angle is formed by two rays that share a common endpoint.

Front

Solve for y: GH = 7y + 3, HI = 3y - 5, GI = 9y + 7. What is the value of y?

Back

y = 9.

Front

What is the formula for the distance between two points in a plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).
