True. One slope is the negative reciprocal of the other slope.
Examples: slope 1/3 so perpendicular slope is -3. slope -2/3 so perpendicular slope is 3/2. slope 4 so perpendicular slope is -1/4.
The intersection of the diagonals of a kite form 90 degree (right) angles. This means that they are perpendicular.
The longer diagonal of a kite bisects the shorter one. This means that the longer diagonal cuts the shorter one in half.
Slope is the measure of steepness of a line.
Slope of a curve: The slope of a curve is the slope of a line tangent to a particular point on the graph of the curve.
Slope-intercept form: An equation of the form y = mx + b, where m is the slope and b is the y-intercept.
