What is the area of a triangle with vertices at (-3 3) (-3,2) and (1,2)?
d1i1m1o1n [39]
This is a right triangle, so first find the distance between the two legs...

Points where the numbers are the same indicate a point that is on the same axis as the other

(-3, 3) and (-3, 2) have a distance of 1


(-3,2) and (1,2) have a distance of 4

The area formula for a triangle is 1/2bh and in this case 1/2(1)(4) = 2

The area is 2
