area of a triangle given 2 sides and an angle code example

Example 1: how to find the area of a triangle

#this is the code to find the area of a parrelogram and triangle
#change the numbers to select what height and base your shape is

b = 3 #b is base 
h = 3 #h is height (middle)


t = 5 #this is the base of the triangle
i = 5 #and this is the height
p = t*i #dont touch this


print("this is the area of the parrelogram")
print(b * h)

m = input("do you want to calculate a triangle? (space before answer)") 

print(m)

if m == " yes":
    print ("this is the area of the triangle that you inputed")
    print (p/2)
else:
    print("ok")

Example 2: how to find a point on a triangle with only sides

known sides AB, BC, AC
known points A(x, y), B(x, y)
unknown points C(x, y)

AC² - BC² = ((Ax - Cx)² + (Ay - Cy)²) - ((Bx - Cx)² + (By - Cy)²)


Goal: 

C.x = ?
C.y = ?
