Front

What is a rigid motion in geometry?

Back

A transformation that preserves distance and angle measures, including rotation, reflection, and translation.

Front

Which transformation is NOT a rigid motion?

Back

Dilation is not a rigid motion because it changes the size of the figure.

What is the midpoint formula for a line segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

Find the midpoint of the line segment with endpoints (3,9) and (5,9).

Back

The midpoint is (4,9).

Front

What is the converse of a conditional statement?

Back

The converse of a statement 'If P, then Q' is 'If Q, then P'.

Front

Given the conditional 'If Jose eats fish, then he has an allergic reaction', what is the converse?

Back

If Jose has an allergic reaction, then he ate fish.

Front

What is the definition of dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure but maintains its shape.

Front

What does it mean for an angle to be acute?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is the measure of angle Z if it is given as 83 degrees?

Back

Angle Z measures 83 degrees.

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.
