# a. (look in the picture for the question).b. Complete the proportion to compare the first two triangles.

b/c = ?/?

c. Cross multiply ratios in part b to get simplified answer.

d. Complete the proportion to compare the first and third triangles.

c/a = ?/?

e. Cross Multiply ratios in part d to get simplified answer

f. Complete the steps to add the equations from part c and e.

Part c: b^2=_____________

Part e: a^2=_____________

a^2+b^2=________

g. Factor out a common factor from part f.

h. Finally, replace the expression inside the parentheses with one variable and then simplify the equation to a familiar form. HINT: look at large triangle at the top of this problem.

(The red line in the big triangle is the altitude from vertex C to side c to create two new triangles, BCD and ACD)
