Question

Find the area of the triangle formed by joining the midpoints of the sides of the triangle whose vertices are (0,-1), (2,1), and (0,3). Find the ratio of this area to the area of the given triangle.​

Answer 1

Hey dude,it is very simple

veritces of trianles are given.

take out the vertices of mid point

vertices of mid point=(0+2/2,1-1/2),(2+0/2,3+1/2),0+0/2,3-1/2)

now after taking out this , simply take out the area by using the formula.

taking out both the area of triangles, simplly divide ,to get the ratio

hope it helps you, Neha ☺️

Answer 2

Verticles of traingles are given .Take out the verticles of the mid point =(0+2/2 ,1-1/2) , (2+0/2,3+1/2),(0+0/2,3-1/2)

Now after taking out this, simply take out the area by using this formula .
