The triangle region include the vertices of a triangle true or false

True

Step-by-step explanation:

The interior of a triangle includes its vertices. The triangular regain includes the vertices of the corresponding triangle. The vertices of a triangle are three collinear points.

I hope this is good enough:

answer: i think it is (1,-2)

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
