Using a ruler and a pair of compasses only, construct 1. Triangle ABC with/AB/ -10com, angle ABC-30° andangle CAB=60
ii, a perpendicular from the point to meet the line AB at P.
bi. Extend the line CP to the point D such that IABI=/BD/.
11, Join A to D and B to D
iil, Measure IAC/ and /AD/
type of quadrilateral is ABCD?
c. What type of quadrilateral is ABCD

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

maybe i can

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
