Draw a figure and describe the locus of points that are 20 cm from point P and 7 cm from a line perpendicular to PQ (with a line over it; I can't do the signs) at point Q, for PQ = 14 cm.
When Hiro has to leave the house for a while, he tethers his mischievous puppy to the corner of a shed in the middle of his large backyard that is 10 ft by 7 ft. The tether is 14 feet long. Sketch the locus of points in the yard that the puppy can reach.
Please, hurry and help! I'm on a deadline!
