Question

What shape can you make with A(−8,5), B, left parenthesis, minus, 3, comma, 8, right parenthesisB(−3,8), C, left parenthesis, 5, comma, 8, right parenthesisC(5,8), D, left parenthesis, 5, comma, 1, right parenthesisD(5,1), E, left parenthesis, minus, 3, comma, 1, right parenthesisE(−3,1)

Answer 1

Those five points are the vertices of a convex pentagon. In fact B(−3,8), C(5,8), D(5,1), E(−3,1) are the corners of a rectangle (BC is horizontal length 8, CD is vertical length 7, DE is horizontal length 8, EB is vertical length 7), and A(−8,5) is attached to that rectangle by segments AB and AE. So the shape is a rectangle BCDE with a triangular “wedge” ABE on the left — a convex pentagon (a “house”-shaped figure).
