How do you find the area of a triangle?
Area of a triangle = ½ base X height
Example 1
A = ½ (7X4)
A= ½(28)
A= 14 units2
Example 2A= ½ (5X12)
A = ½ (60)
A = 30 units2

What is the height of triangle ABC if the area is 24 in2 and the base is 12 in ?
A = ½ (bXh)
24 = ½ (12Xh)
24 = 6h
4 = h
What is the base of triangle LMN if the area is 14 cm2 and the height is 2cm?
14 = ½(bx2)

a. Measure of angle CDE = Measure of angle DEF
b. Measure of angle CDE + EDF + EFD = 180 degrees
c. Measure of angle EFD is less than measure of angle AED
and
Measure of angle FED is less than measure of angle BFD
