Multiple Select

Lines m and n are perpendicular. Which of the following statements are true regarding lines m and n? Select two that apply

• Lines m and n form four right angles

• Lines m and n intersect at a single point

• Lines m and n are equidistant from each other

• Lines m and n form two acute angles and two obtuse angles.

Multiple Select

Mickey draws two distinct intersecting lines, p and q. Which conclusions must be true? Select the three that apply.

• Lines p and q are not parallel.

• Lines p and q form four angles.

• Lines p and q are perpendicular.

• Lines p and q share a common point.

Multiple Choice

The basic concepts of "line" and "point" can be used to define a ray. A ray is a portion of a line that starts at a point and extends in a particular direction. How can this definition of a ray be used to formulate a definition of an angle?

• An angle is the intersection of two rays at a common point.

• An angle is the figure formed by two rays that lie on the same line.

• An angle is a special kind of ray that points in two particular directions.

• An angle is a figure formed by two rays extending from a common point.

Multiple Choice

Look at the trapezoid shown below. Which transformation carries the trapezoid onto itself?

• a reflection across the line y=0

• a rotation of 180 degrees about the point (-1,0)

• a rotation of 180 degrees about the origin

• a reflection across the line x= -1

Multiple Select

Consider the rectangle shown. Which of the following combinations of transformations map the rectangle onto itself? Select ALL that apply.

• a reflection across the y-axis, followed by a reflection across the x-axis

• a counterclockwise rotation of 180° about the origin, followed by a reflection across the line y = 1

• a reflection across the y-axis, followed by a clockwise rotation of 90° about the origin

• a clockwise rotation of 90° about the origin, followed by a counterclockwise rotation of 270° about the origin
