What is the area of a triangle
A=hb/2
A=bh/2
A=2/hb
A=2/bh
When base and height are given, what formula do you use?
A = 1/2 / base x height
A = base x 1/2 x height
A = 1/2 x height x base
A = height / base x 1/2
How do you find the third side of a triangle when given the area?
a^2 x c^2 = b^2
c^2 + b^2 = a^2
b^2 x a^2 = c^2
a^2 + b^2 = c^2
What is the Pythagorean Therom?
A = h b/2
a^2 + b^2 = c^2
A = 1/2 bh
a^2 x b^2 = c^2
Find the area
area = 1/2 x 6 x 5 = 15
area = 1/2 x 2 x 7 = 14
area = 5 x 5 x 1/2 = 15
area = 6 x 7 x 1/2 = 15
Find the area
A = 280 cm
A = 380 cm
A = 360 cm
A = 260 cm
What is the area of a triangle with base = 2 cm and height = 4 cm?
1/2 × 4 × 2 = 8 cm2
1/2 × 8 × 2 = 16 cm2
1/2 × 4 × 2 = 4 cm2
1/2 × 2 × 2 = 4 cm2
What are the 3 numbers in dimensions?
area, base, height
width, length, area
base, height, angle
length, height, width
