Use Cabri Jr. to draw and label three noncollinear points X, Y, and Z.

Use Cabri Jr. to draw two segments and that intersect at a point X.

Use Cabri Jr. to draw a segment and measure it.

Use Cabri Jr. to draw and label segment with midpoint X.

Use Cabri Jr. to draw an angle ABC and measure it. Tell whether the angle is acute, right, or obtuse.

Use Cabri Jr. to draw and label ABC with angle bisector .

Use Cabri Jr. to draw a segment from (0, 0) to (2, 3) and find its length. Use the regular calculator functions to confirm the answer Cabri Jr. gives you.

Use Cabri Jr. to plot points A(1, 3), B(0, 0), and C(3, 1) find mABC.

On your calculator, graph a line segment with endpoints (–2, –7) and (8, 3), and find its length to the nearest 0.01 unit.

On your calculator, graph a vertical line and a horizontal line which intersect at the point (3.5, –0.5).

Use Cabri Jr. to demonstrate the Segment Addition Postulate. (The Segment Addition Postulate states that if points A, B, and X are collinear and X lies on , then AX + XB = AB.)

Use Cabri Jr. to demonstrate the Angle Addition Postulate. (The Angle Addition Postulate states that if D is in the interior of ABC, then mABD + mDBC = mABC.)

Use Cabri Jr. to draw a segment in the coordinate plane and plot its midpoint. View the coordinates of all three points and verify that they satisfy the midpoint formula. Then move the endpoints around and verify the formula again.

Recall: If A(x₁,y₁) and B(x₂, y₂) are two points, then the midpoint formula gives the coordinates of the midpoint of are

Use Cabri Jr. to show that the two angles of a linear pair are always supplementary.

Use Cabri Jr. to demonstrate that vertical angles are congruent.
