Answer:
B. [tex]\dfrac{1}{2}ab[/tex]
Step-by-step explanation:
Given the proof below:
Proof of Pythagorean theorem.
Step 1: Given yellow triangle abc
Step 2: Construct 3 triangles congruent to yellow triangle abc.
Step 3:[tex](a + b)^2 = c^2 + 4(\dfrac{1}{2}ab)[/tex]
Step 4: [tex]a^2 + 2ab + b^2 = c^2 + 2ab[/tex]
Step 5: [tex]a^2 + b^2 = c^2[/tex]
Since Area of a Triangle =[tex]\frac{1}{2}X$Base X Height[/tex]
The expression that represents the area of each triangle is Option B.
