3. The shapes L, R, and N are alike because they each have exactly four sides, therefore called
quadrilaterals. They are each quadrilaterals because L is a parallelogram, N is a parallelogram,
and R is a trapezoid.

b) Each of the points on ABCD corresponds to the points on ABCD. The corresponding
letters have the same angle measurements over the line of reflection. Also, all of the side lengths

b) V = lwh
v = 10 * 4 * 5
V = 200 cm3
V = lwh
V=8*5*5
V = 200 cm3
V = lwh
V = 20 * 2 * 5

of all the sides of the rectangle.
P = 2l + 2w
P = 2 (20ft) + 2 (30ft)
P = 100 ft fencing

thinking that the area depends on the size of the angles, but it does not. The area of a triangle is
