Prove that opposite sides of a parallelogram are congruent. be sure to create and name the appropriate geometric figures.

If either sides are flipped turn dialted or translated they will all way's be congruent due to the orignal shape being the same as all matters of form changed of this object

m∠a is 90°

m∠b is 40°

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
