Front

What is the solution for x in the equation that results in 13?

Back

x = 13

Front

What does it mean for points S, V, and P to be coplanar?

Back

Points S, V, and P lie on the same plane.

Front

Identify the vertex angle in a triangle labeled A, B, and C.

Back

The vertex angle is

Front

How do you find the y-coordinate of the midpoint of a line segment?

Back

The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

Front

In a triangle, which segment is typically referred to as the base?

Back

The base is often the segment opposite the vertex angle, in this case, Segment AB.

Front

What is the definition of collinear points?

Back

Collinear points are points that lie on the same straight line.

Front

What is the formula for finding the midpoint of a line segment?

Back

Midpoint M = ((x1 + x2)/2, (y1 + y2)/2) where (x1, y1) and (x2, y2) are the endpoints.

Front

What is the definition of a vertex in geometry?

Back

A vertex is a point where two or more lines or edges meet.

Front

What does it mean for points to be coplanar?

Back

Coplanar points are points that lie on the same plane.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.
