Question #N99
A triangle has vertices at the points $(0,0), (1,0),$ and $(0,1)$. What is the area of this triangle?
A. $\frac{1}{4}$
B. $\frac{1}{2}$
C. 1
D. 2
Correct Answer is: A
The triangle is a right triangle with a base of 1 and a height of 1. The area of a triangle is given by the formula $\frac{1}{2}bh$. Therefore, the area of the triangle is $\frac{1}{2}(1)(1) = \frac{1}{2}$.
