What shapes do you see?

The Trapezoid Area & Perimeter

Trapezoid Parallel sides What is a trapezoid? A quadrilateral with exactly 1 pair of parallel sides Parallel sides

Trapezoid Perimeter ADD UP ALL THE SIDES!!! 5 m 3 m 3 m 4 m

Trapezoid Parallel sides What is a trapezoid? A quadrilateral with exactly 1 pair of parallel sides Parallel sides

What do we mean by parallel? Trapezoid What do we mean by parallel? These lines will eventually intersect. (cross) These lines will never intersect. They are PARALLEL

Trapezoid Where do we see parallel lines?

Trapezoid bases. base 1 base 1 base 2 base 2 We call the parallel sides the… bases. base 1 base 1 base 2 base 2

Label the bases of each trapezoid.

How do we measure height? 7 ft 6 in 8 ft

Trapezoid Height So if we see a trapezoid, which measurement represents the HEIGHT? 2.5 ft 4 ft

Trapezoid Area = base 1 = base 2 = height

7 ft 5 ft 4 ft 5 ft 3 ft

15 ft 7 ft 6 ft 7 ft 9 ft

3 cm 10 cm 8 cm 10 cm 13 cm

10 cm 4 cm 16 cm 8 cm 4 16 + 8 2 10 cm 20 8 80 10 8 = 2 square cm
