- Q1
To prove 4 points create a parallelogram, use...
slope to show opposite sides are congruent so they are parallel
slope to show opposite sides have negative reciprocal slopes so they are parallel
slope to show consecutive sides have reciprocal slopes so they are parallel
slope to show opposite sides have the same slope so they are parallel
120sGEO-G.GPE.4 - Q2
To prove 4 points create a rectangle, use...
slope to show opposite sides have negative reciprocal slopes so they are parallel and consecutive sides have the same slope so they are perpendicular and form right angles.
slope to show consecutive sides have reciprocal slopes so they are parallel and consecutive sides have negative reciprocal slopes so they are perpendicular and form right angles
slope to show opposite sides have the same slope so they are parallel and consecutive sides have negative reciprocal slopes so they are perpendicular and form right angles
slope to show opposite sides are congruent so they are parallel and consecutive sides have negative reciprocal slopes so they are perpendicular and form right angles
120sGEO-G.GPE.4 - Q3
To prove 4 points create a trapezoid, use...
slope to show consecutive sides have reciprocal slopes so they are parallel and 1 set of opposite sides do not have the same slope so they are not parallel
slope to show opposite sides have negative reciprocal slopes so they are parallel and 1 set of opposite sides do not have the same slope so they are not parallel
slope to show 1 set of opposite sides have the same slope so they are parallel and 1 set of opposite sides do not have the same slope so they are not parallel
slope to show opposite sides are congruent so they are parallel and 1 set of opposite sides do not have the same slope so they are not parallel
120sGEO-G.GPE.4 - Q4
To prove 3 points create an isosceles triangle, use...
slope () to show 2 sides have the same slope and are parallel and meet at a right angle
slope () to show 2 sides have negative reciprocal slopes and are perpendicular and meet at a right angle
distance () to show 2 sides have the same length
distance () to show 2 sides have negative reciprocal slopes and are perpendicular and meet at a right angle
120sGEO-G.GPE.4 - Q5
To prove 3 points create a right triangle, use...
slope () to show 2 sides have negative reciprocal slopes and are perpendicular and meet at a right angle
slope () to show 2 sides have the same slope and are parallel and meet at a right angle
slope () to show 2 sides have negative reciprocal slopes and are perpendicular and meet at a right angle
slope () to show 2 sides have equal slopes and are perpendicular and meet at a right angle
