• Which quadrilaterals have 4 right angles? _____ The quadrilaterals in the section where the circles overlap have _ pairs of opposite sides that are parallel, _sides of equal length, and _ right angles. So, __ are in both circles. What information am I given? the circles labeled __ and __ Plan What is my plan or strategy? Thus the center of each circle will be moving in the negative y-direction at a rate of h 1 2gt 2 (see [1]). Adding in this shift for the y-values of each circle, we ﬁnd the equation of each expanding circle at a given time t is x2 +(y h+ 1 2 gt2)2 = v2t2. (8) Figure 4 shows some of these circles for varying values of t.
