AREA OF TRIANGLES Section 10.1b

Warm Up Find each missing side.

Acute Triangle: Height is IN the triangle.

Right Triangle: Height is ON the triangle.

Obtuse Triangle: Height is OUTSIE the triangle.

Find the exact area of each triangle. Exact means no rounding or decimal answers.

Area of a Trapezoid

Find the height of a trapezoid with an area of 287 in 2 and bases of 38 in and 44 in.

Find b 2 of the trapezoid, in which A = 231 mm 2.

b1 b2 Median Median is (b1 + b2)/2 Area is (Median) (height)

Find the area.
