Common Assessment Review

Front

What is the measure of the missing angle if one angle is 130°?

Back

50°

Front

How do you find the coordinates of a point A(4,2) reflected over the line x=2?

Back

The coordinates of A' are (0,2). Use the midpoint formula to find the reflection.

Front

What is the order and angle of rotation for a flower with order 6?

Back

Order 6, 60 degrees.

Front

What are the new coordinates of point B(5,-2) after translating 3 units to the right and 2 units down?

Back

The new coordinates are (8,-4).

Front

If lines a and b are parallel and cut by transversal t, and m∠1 = 80°, what is m∠2 if it is a linear pair with angle 1?

Back

m∠2 = 100°.

Front

Define reflection in geometry.

Back

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

Front

What is the midpoint formula?

Back

The midpoint formula is ((x1 + x2)/2, (y1 + y2)/2).

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, summing to 180°.

Front

Explain the concept of angle rotation.

Back

Angle rotation is the turning of a figure around a fixed point, measured in degrees.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.
