Midpoint Quadrilaterals

Video Instructions - Watch this if you are having any difficulties following the instructions.

Square

Step 1: Use the midpoint tool to find the midpoint of all four sides of the square Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the square. Do not connect the midpoints across from each other Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.

Trapezoid

Step 1: Use the midpoint tool to find the midpoint of all four sides of the trapezoid. Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the trapezoid. Do not connect the midpoints across from each other. Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.

Parallelogram

Step 1: Use the midpoint tool to find the midpoint of all four sides of the parallelogram. Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the parallelogram. Do not connect the midpoints across from each other. Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.

Quadrilateral

Step 1: Use the midpoint tool to find the midpoint of all four sides of the quadrilateral. Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the original quadrilateral. Do not connect the midpoints across from each other. Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.

Rectangle

Step 1: Use the midpoint tool to find the midpoint of all four sides of the rectangle. Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the rectangle. Do not connect the midpoints across from each other. Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.

Rhombus

Step 1: Use the midpoint tool to find the midpoint of all four sides of the rhombus. Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the rhombus. Do not connect the midpoints across from each other. Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.

Kite

Step 1: Use the midpoint tool to find the midpoint of all four sides of the kite. Step 2: Use the segment tool to connect each midpoint to the other midpoints next to them to draw the "midpoint quadrilateral" of the kite. Do not connect the midpoints across from each other. Step 3: Use the distance tool to find the lengths of the four sides of the new quadrilateral. Step 4: Answer the questions in the pear deck.
