WebNov 14, 2024 · Let's draw a line from one of the top vertices that falls on the bottom base a a a at an angle of 90 ° 90\degree 90°. (Observe how for obtuse trapezoids like the one in the right picture above the height h h h falls outside of the shape, i.e., on the line containing a a a rather than a a a itself. Nevertheless, what we describe further down still holds for such … WebThe order of rotational symmetry of a regular polygon is the same as the number of sides of the polygon. You can also deduce the order of rotational symmetry by knowing the smallest angle you can rotate the shape through to look the same. 180° = order 2, 120° = order 3, 90° = order 4. The product of the angle and the order would be 360°.
Rotating shapes about the origin by multiples of 90° - Khan …
WebSolution method 1: The visual approach. We can imagine a rectangle that has one vertex at the origin and the opposite vertex at A A. A rotation by 90^\circ 90∘ is like tipping the rectangle on its side: Now we see that the image of A (3,4) A(3,4) under the rotation is A' ( … WebExample 5: cubic graph.
