Year 1 Lesson 23-A In-class Exercise - Page 2
You are given 3 points (A, B and C) for each shape.
The points given go clockwise (
↷
) around the figure with D being the next point after point C.
Plot these points.
Find the offset of point A from point B in X and Y.
(Subtract the X and Y coordinates of B
from
A. This is
A minus B
)
Apply these offsets to point C to determine point D
Plot your new point D and draw the shape.
Does it look like the shape you want?
