Right angles are created by perpendicular lines. You first have to find the slopes of the lines. You know lines are perpendicular when the slopes are negative reciprocals. For example: If you find the slope of Line AB to be -2, in order for the lines to form right angles, the following line would have to be 1/2. So getting back to your question, calculate the slopes and show they are negative reciprocals. Hope I Helped!

If you are subtracting the negative from the positive, the answer will be positive. If you are subtracting the positive from the negative, the answer will be negative.

A negative times a positive is a negative and that negative times a negative would = a positive. So the answer would be a positive number. *<:)

No. A positive times a negative is always negative. A negative times a negative is always a positive.

If a i positive, -a is negative; if a is negative, -a is positive.

The slopes of perpendicular lines are reciprocals of each other. For example. if one line had an equation like y= 2x+4 then the perpendicular's slope would be y=x/2+4 -- they are reciprocals of each other.

Only by coincidence. Two lines on a graph are perpendicular if and only if one slope is the negative reciprocal of the other: meaning that if one line has a slope of 3/2, the other would have to have a gradient of -2/3.

A positive times a negative is negative, so positive 3 times negative 4 would be negative 12.

When two lines are perpendicular, their slopes are negative reciprocals. In the example, the perpendicular to y= (1/21) x would be y = -21 x For y = 2x, the perpendicular would be y= -½ x You invert the fraction and change the sign.

If a negative is divided by a positive, the resulting quotient will be negative. If a negative is divided by another negative, the quotient would be positive.

No, a negative times a negative would be a positive and a positive times a positive would also be positive, and anything multiplied by zero would still be zero

you would get a negative

A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4

You would first prove that 3 of the sides are the same size (The 4th is automatically the same size as the other three). Then, you would prove that there are three right angles in the shape, using the slopes (If lines make a right angle, they are perpendicular and their slopes are negative reciprocals of each other.).

a positive plus a negative is a positive example 9-(-2) you would change the double negative to a positive hope this helped :)

You could have O positive or negative blood or A positive or negative blood.

positive because if it would be negative it would be way on another subject.

a positive denotation would be slim and a negative one would be scrawny

negative multiplied by negative would be positive

negative

a negative

positive

If you are talking about the multiplication rules than they would be; a negative times a negative is a positive a negative times a positive is a negative

No, because if the positive was 8, and the negative was -4, the difference would be positive four.
