A rhombus is mainly defined as: "A parallelogram in which all sides are equal".
This means that, in a rhombus:
1- All sides are equal
2- Each two opposite angle are equal
Based in this:
"<span>A figure has four sides measuring 10 centimeters, and two pair of opposite congruent angles." can be classified as a rhombus.
Hope this helps :)

A^2 + b^2 = c^2 in right triangles.
4^2 + b^2 = 8.5^2
16 + b^2 = 72.25
b^2 = 56.25
b = 7.5
This line crosses the point (4,5)so we can make an equation to find the slope:

hope this helps
