180 Degrees In Math
If this figure is rotated 180 about the origin find the vertices of the rotated figure and graph.
180 degrees in math. Given a 180 degree rotation r o around the origin o of a coordinate system and a point p with coordinates a b it is generally said that r o p is the point with coordinates a b. A rotation of 180 degrees around o is the rigid motion so that if p is any point in the plane p o and rotation p are collinear i e lie on the same line. Angles that measure exactly 90 degrees are called right angles. The larger angle at the intersection of a vertical and a horizontal line creates a 270 degree angle.
A straight line creates a 180 degree angle. An angle that is exactly 180 degrees is called a straight angle this appears as a straight line. 180 degrees is a straight line. Angles that measure less than 90 degrees are called acute angles.
Let p 2 2 q 1 2 r 2 4 and s 3 4 be the vertices of a four sided closed figure. Let us look at some examples to understand how 180 degree rotation about the origin can be done on a figure.
