What is a algebra mapping?
A mapping consists of two sets and a rule for assigning to each element in the first set one or more elements in the second set. We say that A is mapped to B and write this as m: A→B.
What is the rule for a pair of perpendicular lines?
They intersect at 90 degrees
What are the interior angles of a triangle that has sides of 2 cm by 4 cm by 3 cm?
Using the cosine rule they are 28.96 degrees, 104.47 degrees and 46.57 degrees which all add up to 180 degrees.
Are all triangles 180 degrees and what rule is it?
Yes the 3 interior angles of any triangle always add up to 180 degrees
How do you rotate a figure 270 degrees?
Rotating a figure 270 degrees is like rotating the figure to the left 90 degrees. I am not sure what formula or rule you use. *Joe Jonas Rocks*
What do you think the mapping rule is for a rotation of 270 degrees clockwise?
It is multiplication by the 2x2 matrix 0 1-1 0
Rule for 90 degree clockwise rotation?
we swap the co-ordinates and give the new y co-ordinate the opposite sign.90 degrees clockwise(y, -x)
What rule represents a 270 clockwise rotation about the origin?
270 rule represent a 270 rotation to the left which is very easy
Rule for 180 degree clockwise rotation?
To rotate a figure 180 degrees clockwise, you can achieve this by first reflecting the figure over the y-axis and then reflecting it over the x-axis. This double reflection effectively rotates the figure 180 degrees clockwise around the origin.
What is the rule for 270 degree counter clockwise rotation?
The effect of the rotation is the same as that of a 90 degree clockwise rotation. In matrix notation, it is equivalent to [post-]multiplication by the 2x2 matrix: { 0 1 } {-1 0 }
What is the rule for a 180 degree counterclockwise rotation?
First of all, if the rotation is 180 degrees then there is no difference clockwise and anti-clockwise so the inclusion of clockwise in the question is redundant. In terms of the coordinate plane, the signs of all coordinates are switched: from + to - and from - to +. So (2, 3) becomes (-2, -3), (-2, 3) becomes (2, -3), (2, -3) becomes (-2, 3) and (-2, -3) becomes (2, 3).
Rule for 90 degrees counterclockwise rotation?
(x,y)-> (-y,x)
What is the symbolic rule for a 45 degree rotation clockwise around the origin?
(x; y) --> (x.cos45 + y.sin45; x.sin45 - y.cos45)
What is the rule for a 270 degree clockwise rotation?
(x,y) to (x,-y). You would keep the x the same, but turn the y negative. This is actually the rule for a 90 degree counterclockwise rotation, but they're the same thing, they would go to the same coordinates.
What transformation is represented by the rule (x y) (y -x)?
It is an anticlockwise rotation through 90 degrees.
How do you find 270 degree clockwise rotation?
(x,y) to (x,-y). You would keep the x the same, but turn the y negative. This is actually the rule for a 90 degree counterclockwise rotation, but they're the same thing, they would go to the same coordinates.
what is the image of the point (-2,7) after a rotation of 180 counterclockwise about the origin?
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
