Geometry Chap 2 section 2 (Fri) Area of Tri, Parral, Trap, cplx

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 * (base1 + base2) * height

Front

Calculate the area of a triangle with a base of 10 cm and a height of 5 cm.

Back

Area = 1/2 * 10 * 5 = 25 cm²

Front

Calculate the area of a trapezoid with bases of 8 cm and 12 cm, and a height of 5 cm.

Back

Area = 1/2 * (8 + 12) * 5 = 50 cm²

Front

What is the area of a parallelogram?

Back

Area = base * height

Front

Calculate the area of a parallelogram with a base of 6 cm and a height of 4 cm.

Back

Area = 6 * 4 = 24 cm²

Front

What is the difference between a triangle and a trapezoid?

Back

A triangle has three sides and three angles, while a trapezoid has four sides with at least one pair of parallel sides.

Front

What is the area of a triangle with a base of 12 ft and a height of 8 ft?

Back

Area = 1/2 * 12 * 8 = 48 ft²

Front

What is the area of a trapezoid with bases of 10 cm and 14 cm, and a height of 6 cm?

Back

Area = 1/2 * (10 + 14) * 6 = 72 cm²

Front

How do you find the height of a triangle if you know the area and base?

Back

Height = (2 * Area) / base
