Since every triangle can be split into two triangles simply by drawing a line from any vertex to the side opposite that vertex, the answer to the question is that there can be no rule to find a number that is infinite.
index of any digit is 0 then it is equal to one according to mathematics's rule. therefore a degree is equal to 1.
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.
Which transformations could have been used to move the platter to the new location? A. a translation 9 units left and a translation 3 units down B. a reflection across MN and a translation 4 units left C. a reflection across MN and a translation 8 units left D. a rotation 180° clockwise about N and a translation 4 units left
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 }
(x; y) --> (x.cos45 + y.sin45; x.sin45 - y.cos45)
we swap the co-ordinates and give the new y co-ordinate the opposite sign.90 degrees clockwise(y, -x)
(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.
270 rule represent a 270 rotation to the left which is very easy
(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.
plz awnser this
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.
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).
It is multiplication by the 2x2 matrix 0 1-1 0
Very simple. Do nothing!Very simple. Do nothing!Very simple. Do nothing!Very simple. Do nothing!
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
